The IAmazonEC2 type exposes the following members

Methods

NameDescription
Public Method AcceptVpcPeeringConnection(AcceptVpcPeeringConnectionRequest) Accept a VPC peering connection request. To accept a request, the VPC peering connection must be in the pending-acceptance state, and you must be the owner of the peer VPC. Use the DescribeVpcPeeringConnections request to view your outstanding VPC peering connection requests.
Public Method AcceptVpcPeeringConnectionAsync(AcceptVpcPeeringConnectionRequest, CancellationToken) Initiates the asynchronous execution of the AcceptVpcPeeringConnection operation.
Public Method AllocateAddress() Acquires an Elastic IP address.

An Elastic IP address is for use either in the EC2-Classic platform or in a VPC. For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

Public Method AllocateAddress(AllocateAddressRequest) Acquires an Elastic IP address.

An Elastic IP address is for use either in the EC2-Classic platform or in a VPC. For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

Public Method AllocateAddressAsync(AllocateAddressRequest, CancellationToken) Initiates the asynchronous execution of the AllocateAddress operation.
Public Method AssignPrivateIpAddresses(AssignPrivateIpAddressesRequest) Assigns one or more secondary private IP addresses to the specified network interface. You can specify one or more specific secondary IP addresses, or you can specify the number of secondary IP addresses to be automatically assigned within the subnet's CIDR block range. The number of secondary IP addresses that you can assign to an instance varies by instance type. For information about instance types, see Instance Types in the Amazon Elastic Compute Cloud User Guide. For more information about Elastic IP addresses, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

AssignPrivateIpAddresses is available only in EC2-VPC.

Public Method AssignPrivateIpAddressesAsync(AssignPrivateIpAddressesRequest, CancellationToken) Initiates the asynchronous execution of the AssignPrivateIpAddresses operation.
Public Method AssociateAddress(AssociateAddressRequest) Associates an Elastic IP address with an instance or a network interface.

An Elastic IP address is for use in either the EC2-Classic platform or in a VPC. For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

[EC2-Classic, VPC in an EC2-VPC-only account] If the Elastic IP address is already associated with a different instance, it is disassociated from that instance and associated with the specified instance.

[VPC in an EC2-Classic account] If you don't specify a private IP address, the Elastic IP address is associated with the primary IP address. If the Elastic IP address is already associated with a different instance or a network interface, you get an error unless you allow reassociation.

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error.

Public Method AssociateAddressAsync(AssociateAddressRequest, CancellationToken) Initiates the asynchronous execution of the AssociateAddress operation.
Public Method AssociateDhcpOptions(AssociateDhcpOptionsRequest) Associates a set of DHCP options (that you've previously created) with the specified VPC, or associates no DHCP options with the VPC.

After you associate the options with the VPC, any existing instances and all new instances that you launch in that VPC use the options. You don't need to restart or relaunch the instances. They automatically pick up the changes within a few hours, depending on how frequently the instance renews its DHCP lease. You can explicitly renew the lease using the operating system on the instance.

For more information, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide.

Public Method AssociateDhcpOptionsAsync(AssociateDhcpOptionsRequest, CancellationToken) Initiates the asynchronous execution of the AssociateDhcpOptions operation.
Public Method AssociateRouteTable(AssociateRouteTableRequest) Associates a subnet with a route table. The subnet and route table must be in the same VPC. This association causes traffic originating from the subnet to be routed according to the routes in the route table. The action returns an association ID, which you need in order to disassociate the route table from the subnet later. A route table can be associated with multiple subnets.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

Public Method AssociateRouteTableAsync(AssociateRouteTableRequest, CancellationToken) Initiates the asynchronous execution of the AssociateRouteTable operation.
Public Method AttachClassicLinkVpc(AttachClassicLinkVpcRequest) Links an EC2-Classic instance to a ClassicLink-enabled VPC through one or more of the VPC's security groups. You cannot link an EC2-Classic instance to more than one VPC at a time. You can only link an instance that's in the running state. An instance is automatically unlinked from a VPC when it's stopped - you can link it to the VPC again when you restart it.

After you've linked an instance, you cannot change the VPC security groups that are associated with it. To change the security groups, you must first unlink the instance, and then link it again.

Linking your instance to a VPC is sometimes referred to as attaching your instance.

Public Method AttachClassicLinkVpcAsync(AttachClassicLinkVpcRequest, CancellationToken) Initiates the asynchronous execution of the AttachClassicLinkVpc operation.
Public Method AttachInternetGateway(AttachInternetGatewayRequest) Attaches an Internet gateway to a VPC, enabling connectivity between the Internet and the VPC. For more information about your VPC and Internet gateway, see the Amazon Virtual Private Cloud User Guide.
Public Method AttachInternetGatewayAsync(AttachInternetGatewayRequest, CancellationToken) Initiates the asynchronous execution of the AttachInternetGateway operation.
Public Method AttachNetworkInterface(AttachNetworkInterfaceRequest) Attaches a network interface to an instance.
Public Method AttachNetworkInterfaceAsync(AttachNetworkInterfaceRequest, CancellationToken) Initiates the asynchronous execution of the AttachNetworkInterface operation.
Public Method AttachVolume(AttachVolumeRequest) Attaches an EBS volume to a running or stopped instance and exposes it to the instance with the specified device name.

Encrypted EBS volumes may only be attached to instances that support Amazon EBS encryption. For more information, see Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.

For a list of supported device names, see Attaching an EBS Volume to an Instance. Any device names that aren't reserved for instance store volumes can be used for EBS volumes. For more information, see Amazon EC2 Instance Store in the Amazon Elastic Compute Cloud User Guide.

If a volume has an AWS Marketplace product code:

  • The volume can be attached only to a stopped instance.
  • AWS Marketplace product codes are copied from the volume to the instance.
  • You must be subscribed to the product.
  • The instance type and operating system of the instance must support the product. For example, you can't detach a volume from a Windows instance and attach it to a Linux instance.

For an overview of the AWS Marketplace, see Introducing AWS Marketplace.

For more information about EBS volumes, see Attaching Amazon EBS Volumes in the Amazon Elastic Compute Cloud User Guide.

Public Method AttachVolumeAsync(AttachVolumeRequest, CancellationToken) Initiates the asynchronous execution of the AttachVolume operation.
Public Method AttachVpnGateway(AttachVpnGatewayRequest) Attaches a virtual private gateway to a VPC. For more information, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.
Public Method AttachVpnGatewayAsync(AttachVpnGatewayRequest, CancellationToken) Initiates the asynchronous execution of the AttachVpnGateway operation.
Public Method AuthorizeSecurityGroupEgress(AuthorizeSecurityGroupEgressRequest) Adds one or more egress rules to a security group for use with a VPC. Specifically, this action permits instances to send traffic to one or more destination CIDR IP address ranges, or to one or more destination security groups for the same VPC.

You can have up to 50 rules per security group (covering both ingress and egress rules).

A security group is for use with instances either in the EC2-Classic platform or in a specific VPC. This action doesn't apply to security groups for use in EC2-Classic. For more information, see Security Groups for Your VPC in the Amazon Virtual Private Cloud User Guide.

Each rule consists of the protocol (for example, TCP), plus either a CIDR range or a source group. For the TCP and UDP protocols, you must also specify the destination port or port range. For the ICMP protocol, you must also specify the ICMP type and code. You can use -1 for the type or code to mean all types or all codes.

Rule changes are propagated to affected instances as quickly as possible. However, a small delay might occur.

Public Method AuthorizeSecurityGroupEgressAsync(AuthorizeSecurityGroupEgressRequest, CancellationToken) Initiates the asynchronous execution of the AuthorizeSecurityGroupEgress operation.
Public Method AuthorizeSecurityGroupIngress(AuthorizeSecurityGroupIngressRequest) Adds one or more ingress rules to a security group.

EC2-Classic: You can have up to 100 rules per group.

EC2-VPC: You can have up to 50 rules per group (covering both ingress and egress rules).

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

[EC2-Classic] This action gives one or more CIDR IP address ranges permission to access a security group in your account, or gives one or more security groups (called the source groups) permission to access a security group for your account. A source group can be for your own AWS account, or another.

[EC2-VPC] This action gives one or more CIDR IP address ranges permission to access a security group in your VPC, or gives one or more other security groups (called the source groups) permission to access a security group for your VPC. The security groups must all be for the same VPC.

Public Method AuthorizeSecurityGroupIngressAsync(AuthorizeSecurityGroupIngressRequest, CancellationToken) Initiates the asynchronous execution of the AuthorizeSecurityGroupIngress operation.
Public Method BundleInstance(BundleInstanceRequest) Bundles an Amazon instance store-backed Windows instance.

During bundling, only the root device volume (C:\) is bundled. Data on other instance store volumes is not preserved.

This action is not applicable for Linux/Unix instances or Windows instances that are backed by Amazon EBS.

For more information, see Creating an Instance Store-Backed Windows AMI.

Public Method BundleInstanceAsync(BundleInstanceRequest, CancellationToken) Initiates the asynchronous execution of the BundleInstance operation.
Public Method CancelBundleTask(CancelBundleTaskRequest) Cancels a bundling operation for an instance store-backed Windows instance.
Public Method CancelBundleTaskAsync(CancelBundleTaskRequest, CancellationToken) Initiates the asynchronous execution of the CancelBundleTask operation.
Public Method CancelConversionTask(CancelConversionTaskRequest) Cancels an active conversion task. The task can be the import of an instance or volume. The action removes all artifacts of the conversion, including a partially uploaded volume or instance. If the conversion is complete or is in the process of transferring the final disk image, the command fails and returns an exception.

For more information, see Using the Command Line Tools to Import Your Virtual Machine to Amazon EC2 in the Amazon Elastic Compute Cloud User Guide.

Public Method CancelConversionTaskAsync(CancelConversionTaskRequest, CancellationToken) Initiates the asynchronous execution of the CancelConversionTask operation.
Public Method CancelExportTask(CancelExportTaskRequest) Cancels an active export task. The request removes all artifacts of the export, including any partially-created Amazon S3 objects. If the export task is complete or is in the process of transferring the final disk image, the command fails and returns an error.
Public Method CancelExportTaskAsync(CancelExportTaskRequest, CancellationToken) Initiates the asynchronous execution of the CancelExportTask operation.
Public Method CancelImportTask(CancelImportTaskRequest) Cancels an in-process import virtual machine or import snapshot task.
Public Method CancelImportTaskAsync(CancelImportTaskRequest, CancellationToken) Initiates the asynchronous execution of the CancelImportTask operation.
Public Method CancelReservedInstancesListing(CancelReservedInstancesListingRequest) Cancels the specified Reserved Instance listing in the Reserved Instance Marketplace.

For more information, see Reserved Instance Marketplace in the Amazon Elastic Compute Cloud User Guide.

Public Method CancelReservedInstancesListingAsync(CancelReservedInstancesListingRequest, CancellationToken) Initiates the asynchronous execution of the CancelReservedInstancesListing operation.
Public Method CancelSpotFleetRequests(CancelSpotFleetRequestsRequest) Cancels the specified Spot fleet requests.
Public Method CancelSpotFleetRequestsAsync(CancelSpotFleetRequestsRequest, CancellationToken) Initiates the asynchronous execution of the CancelSpotFleetRequests operation.
Public Method CancelSpotInstanceRequests(CancelSpotInstanceRequestsRequest) Cancels one or more Spot instance requests. Spot instances are instances that Amazon EC2 starts on your behalf when the bid price that you specify exceeds the current Spot price. Amazon EC2 periodically sets the Spot price based on available Spot instance capacity and current Spot instance requests. For more information, see Spot Instance Requests in the Amazon Elastic Compute Cloud User Guide.

Canceling a Spot instance request does not terminate running Spot instances associated with the request.

Public Method CancelSpotInstanceRequestsAsync(CancelSpotInstanceRequestsRequest, CancellationToken) Initiates the asynchronous execution of the CancelSpotInstanceRequests operation.
Public Method ConfirmProductInstance(ConfirmProductInstanceRequest) Determines whether a product code is associated with an instance. This action can only be used by the owner of the product code. It is useful when a product code owner needs to verify whether another user's instance is eligible for support.
Public Method ConfirmProductInstanceAsync(ConfirmProductInstanceRequest, CancellationToken) Initiates the asynchronous execution of the ConfirmProductInstance operation.
Public Method CopyImage(CopyImageRequest) Initiates the copy of an AMI from the specified source region to the current region. You specify the destination region by using its endpoint when making the request. AMIs that use encrypted EBS snapshots cannot be copied with this method.

For more information, see Copying AMIs in the Amazon Elastic Compute Cloud User Guide.

Public Method CopyImageAsync(CopyImageRequest, CancellationToken) Initiates the asynchronous execution of the CopyImage operation.
Public Method CopySnapshot(CopySnapshotRequest) Copies a point-in-time snapshot of an EBS volume and stores it in Amazon S3. You can copy the snapshot within the same region or from one region to another. You can use the snapshot to create EBS volumes or Amazon Machine Images (AMIs). The snapshot is copied to the regional endpoint that you send the HTTP request to.

Copies of encrypted EBS snapshots remain encrypted. Copies of unencrypted snapshots remain unencrypted, unless the Encrypted flag is specified during the snapshot copy operation. By default, encrypted snapshot copies use the default AWS Key Management Service (AWS KMS) customer master key (CMK); however, you can specify a non-default CMK with the KmsKeyId parameter.

For more information, see Copying an Amazon EBS Snapshot in the Amazon Elastic Compute Cloud User Guide.

Public Method CopySnapshotAsync(CopySnapshotRequest, CancellationToken) Initiates the asynchronous execution of the CopySnapshot operation.
Public Method CreateCustomerGateway(CreateCustomerGatewayRequest) Provides information to AWS about your VPN customer gateway device. The customer gateway is the appliance at your end of the VPN connection. (The device on the AWS side of the VPN connection is the virtual private gateway.) You must provide the Internet-routable IP address of the customer gateway's external interface. The IP address must be static and can't be behind a device performing network address translation (NAT).

For devices that use Border Gateway Protocol (BGP), you can also provide the device's BGP Autonomous System Number (ASN). You can use an existing ASN assigned to your network. If you don't have an ASN already, you can use a private ASN (in the 64512 - 65534 range).

Amazon EC2 supports all 2-byte ASN numbers in the range of 1 - 65534, with the exception of 7224, which is reserved in the us-east-1 region, and 9059, which is reserved in the eu-west-1 region.

For more information about VPN customer gateways, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide.

You cannot create more than one customer gateway with the same VPN type, IP address, and BGP ASN parameter values. If you run an identical request more than one time, the first request creates the customer gateway, and subsequent requests return information about the existing customer gateway. The subsequent requests do not create new customer gateway resources.

Public Method CreateCustomerGatewayAsync(CreateCustomerGatewayRequest, CancellationToken) Initiates the asynchronous execution of the CreateCustomerGateway operation.
Public Method CreateDhcpOptions(CreateDhcpOptionsRequest) Creates a set of DHCP options for your VPC. After creating the set, you must associate it with the VPC, causing all existing and new instances that you launch in the VPC to use this set of DHCP options. The following are the individual DHCP options you can specify. For more information about the options, see RFC 2132.
  • domain-name-servers - The IP addresses of up to four domain name servers, or AmazonProvidedDNS. The default DHCP option set specifies AmazonProvidedDNS. If specifying more than one domain name server, specify the IP addresses in a single parameter, separated by commas.
  • domain-name - If you're using AmazonProvidedDNS in us-east-1, specify ec2.internal. If you're using AmazonProvidedDNS in another region, specify region.compute.internal (for example, ap-northeast-1.compute.internal). Otherwise, specify a domain name (for example, MyCompany.com). Important: Some Linux operating systems accept multiple domain names separated by spaces. However, Windows and other Linux operating systems treat the value as a single domain, which results in unexpected behavior. If your DHCP options set is associated with a VPC that has instances with multiple operating systems, specify only one domain name.
  • ntp-servers - The IP addresses of up to four Network Time Protocol (NTP) servers.
  • netbios-name-servers - The IP addresses of up to four NetBIOS name servers.
  • netbios-node-type - The NetBIOS node type (1, 2, 4, or 8). We recommend that you specify 2 (broadcast and multicast are not currently supported). For more information about these node types, see RFC 2132.

Your VPC automatically starts out with a set of DHCP options that includes only a DNS server that we provide (AmazonProvidedDNS). If you create a set of options, and if your VPC has an Internet gateway, make sure to set the domain-name-servers option either to AmazonProvidedDNS or to a domain name server of your choice. For more information about DHCP options, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide.

Public Method CreateDhcpOptionsAsync(CreateDhcpOptionsRequest, CancellationToken) Initiates the asynchronous execution of the CreateDhcpOptions operation.
Public Method CreateFlowLogs(CreateFlowLogsRequest) Creates one or more flow logs to capture IP traffic for a specific network interface, subnet, or VPC. Flow logs are delivered to a specified log group in Amazon CloudWatch Logs. If you specify a VPC or subnet in the request, a log stream is created in CloudWatch Logs for each network interface in the subnet or VPC. Log streams can include information about accepted and rejected traffic to a network interface. You can view the data in your log streams using Amazon CloudWatch Logs.

In your request, you must also specify an IAM role that has permission to publish logs to CloudWatch Logs.

Public Method CreateFlowLogsAsync(CreateFlowLogsRequest, CancellationToken) Initiates the asynchronous execution of the CreateFlowLogs operation.
Public Method CreateImage(CreateImageRequest) Creates an Amazon EBS-backed AMI from an Amazon EBS-backed instance that is either running or stopped.

If you customized your instance with instance store volumes or EBS volumes in addition to the root device volume, the new AMI contains block device mapping information for those volumes. When you launch an instance from this new AMI, the instance automatically launches with those additional volumes.

For more information, see Creating Amazon EBS-Backed Linux AMIs in the Amazon Elastic Compute Cloud User Guide.

Public Method CreateImageAsync(CreateImageRequest, CancellationToken) Initiates the asynchronous execution of the CreateImage operation.
Public Method CreateInstanceExportTask(CreateInstanceExportTaskRequest) Exports a running or stopped instance to an S3 bucket.

For information about the supported operating systems, image formats, and known limitations for the types of instances you can export, see Exporting EC2 Instances in the Amazon Elastic Compute Cloud User Guide.

Public Method CreateInstanceExportTaskAsync(CreateInstanceExportTaskRequest, CancellationToken) Initiates the asynchronous execution of the CreateInstanceExportTask operation.
Public Method CreateInternetGateway() Creates an Internet gateway for use with a VPC. After creating the Internet gateway, you attach it to a VPC using AttachInternetGateway.

For more information about your VPC and Internet gateway, see the Amazon Virtual Private Cloud User Guide.

Public Method CreateInternetGateway(CreateInternetGatewayRequest) Creates an Internet gateway for use with a VPC. After creating the Internet gateway, you attach it to a VPC using AttachInternetGateway.

For more information about your VPC and Internet gateway, see the Amazon Virtual Private Cloud User Guide.

Public Method CreateInternetGatewayAsync(CreateInternetGatewayRequest, CancellationToken) Initiates the asynchronous execution of the CreateInternetGateway operation.
Public Method CreateKeyPair(CreateKeyPairRequest) Creates a 2048-bit RSA key pair with the specified name. Amazon EC2 stores the public key and displays the private key for you to save to a file. The private key is returned as an unencrypted PEM encoded PKCS#8 private key. If a key with the specified name already exists, Amazon EC2 returns an error.

You can have up to five thousand key pairs per region.

The key pair returned to you is available only in the region in which you create it. To create a key pair that is available in all regions, use ImportKeyPair.

For more information about key pairs, see Key Pairs in the Amazon Elastic Compute Cloud User Guide.

Public Method CreateKeyPairAsync(CreateKeyPairRequest, CancellationToken) Initiates the asynchronous execution of the CreateKeyPair operation.
Public Method CreateNetworkAcl(CreateNetworkAclRequest) Creates a network ACL in a VPC. Network ACLs provide an optional layer of security (in addition to security groups) for the instances in your VPC.

For more information about network ACLs, see Network ACLs in the Amazon Virtual Private Cloud User Guide.

Public Method CreateNetworkAclAsync(CreateNetworkAclRequest, CancellationToken) Initiates the asynchronous execution of the CreateNetworkAcl operation.
Public Method CreateNetworkAclEntry(CreateNetworkAclEntryRequest) Creates an entry (a rule) in a network ACL with the specified rule number. Each network ACL has a set of numbered ingress rules and a separate set of numbered egress rules. When determining whether a packet should be allowed in or out of a subnet associated with the ACL, we process the entries in the ACL according to the rule numbers, in ascending order. Each network ACL has a set of ingress rules and a separate set of egress rules.

We recommend that you leave room between the rule numbers (for example, 100, 110, 120, ...), and not number them one right after the other (for example, 101, 102, 103, ...). This makes it easier to add a rule between existing ones without having to renumber the rules.

After you add an entry, you can't modify it; you must either replace it, or create an entry and delete the old one.

For more information about network ACLs, see Network ACLs in the Amazon Virtual Private Cloud User Guide.

Public Method CreateNetworkAclEntryAsync(CreateNetworkAclEntryRequest, CancellationToken) Initiates the asynchronous execution of the CreateNetworkAclEntry operation.
Public Method CreateNetworkInterface(CreateNetworkInterfaceRequest) Creates a network interface in the specified subnet.

For more information about network interfaces, see Elastic Network Interfaces in the Amazon Elastic Compute Cloud User Guide.

Public Method CreateNetworkInterfaceAsync(CreateNetworkInterfaceRequest, CancellationToken) Initiates the asynchronous execution of the CreateNetworkInterface operation.
Public Method CreatePlacementGroup(CreatePlacementGroupRequest) Creates a placement group that you launch cluster instances into. You must give the group a name that's unique within the scope of your account.

For more information about placement groups and cluster instances, see Cluster Instances in the Amazon Elastic Compute Cloud User Guide.

Public Method CreatePlacementGroupAsync(CreatePlacementGroupRequest, CancellationToken) Initiates the asynchronous execution of the CreatePlacementGroup operation.
Public Method CreateReservedInstancesListing(CreateReservedInstancesListingRequest) Creates a listing for Amazon EC2 Reserved Instances to be sold in the Reserved Instance Marketplace. You can submit one Reserved Instance listing at a time. To get a list of your Reserved Instances, you can use the DescribeReservedInstances operation.

The Reserved Instance Marketplace matches sellers who want to resell Reserved Instance capacity that they no longer need with buyers who want to purchase additional capacity. Reserved Instances bought and sold through the Reserved Instance Marketplace work like any other Reserved Instances.

To sell your Reserved Instances, you must first register as a seller in the Reserved Instance Marketplace. After completing the registration process, you can create a Reserved Instance Marketplace listing of some or all of your Reserved Instances, and specify the upfront price to receive for them. Your Reserved Instance listings then become available for purchase. To view the details of your Reserved Instance listing, you can use the DescribeReservedInstancesListings operation.

For more information, see Reserved Instance Marketplace in the Amazon Elastic Compute Cloud User Guide.

Public Method CreateReservedInstancesListingAsync(CreateReservedInstancesListingRequest, CancellationToken) Initiates the asynchronous execution of the CreateReservedInstancesListing operation.
Public Method CreateRoute(CreateRouteRequest) Creates a route in a route table within a VPC.

You must specify one of the following targets: Internet gateway or virtual private gateway, NAT instance, VPC peering connection, or network interface.

When determining how to route traffic, we use the route with the most specific match. For example, let's say the traffic is destined for 192.0.2.3, and the route table includes the following two routes:

  • 192.0.2.0/24 (goes to some target A)

  • 192.0.2.0/28 (goes to some target B)

Both routes apply to the traffic destined for 192.0.2.3. However, the second route in the list covers a smaller number of IP addresses and is therefore more specific, so we use that route to determine where to target the traffic.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

Public Method CreateRouteAsync(CreateRouteRequest, CancellationToken) Initiates the asynchronous execution of the CreateRoute operation.
Public Method CreateRouteTable(CreateRouteTableRequest) Creates a route table for the specified VPC. After you create a route table, you can add routes and associate the table with a subnet.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

Public Method CreateRouteTableAsync(CreateRouteTableRequest, CancellationToken) Initiates the asynchronous execution of the CreateRouteTable operation.
Public Method CreateSecurityGroup(CreateSecurityGroupRequest) Creates a security group.

A security group is for use with instances either in the EC2-Classic platform or in a specific VPC. For more information, see Amazon EC2 Security Groups in the Amazon Elastic Compute Cloud User Guide and Security Groups for Your VPC in the Amazon Virtual Private Cloud User Guide.

EC2-Classic: You can have up to 500 security groups.

EC2-VPC: You can create up to 100 security groups per VPC.

When you create a security group, you specify a friendly name of your choice. You can have a security group for use in EC2-Classic with the same name as a security group for use in a VPC. However, you can't have two security groups for use in EC2-Classic with the same name or two security groups for use in a VPC with the same name.

You have a default security group for use in EC2-Classic and a default security group for use in your VPC. If you don't specify a security group when you launch an instance, the instance is launched into the appropriate default security group. A default security group includes a default rule that grants instances unrestricted network access to each other.

You can add or remove rules from your security groups using AuthorizeSecurityGroupIngress, AuthorizeSecurityGroupEgress, RevokeSecurityGroupIngress, and RevokeSecurityGroupEgress.

Public Method CreateSecurityGroupAsync(CreateSecurityGroupRequest, CancellationToken) Initiates the asynchronous execution of the CreateSecurityGroup operation.
Public Method CreateSnapshot(CreateSnapshotRequest) Creates a snapshot of an EBS volume and stores it in Amazon S3. You can use snapshots for backups, to make copies of EBS volumes, and to save data before shutting down an instance.

When a snapshot is created, any AWS Marketplace product codes that are associated with the source volume are propagated to the snapshot.

You can take a snapshot of an attached volume that is in use. However, snapshots only capture data that has been written to your EBS volume at the time the snapshot command is issued; this may exclude any data that has been cached by any applications or the operating system. If you can pause any file systems on the volume long enough to take a snapshot, your snapshot should be complete. However, if you cannot pause all file writes to the volume, you should unmount the volume from within the instance, issue the snapshot command, and then remount the volume to ensure a consistent and complete snapshot. You may remount and use your volume while the snapshot status is pending.

To create a snapshot for EBS volumes that serve as root devices, you should stop the instance before taking the snapshot.

Snapshots that are taken from encrypted volumes are automatically encrypted. Volumes that are created from encrypted snapshots are also automatically encrypted. Your encrypted volumes and any associated snapshots always remain protected.

For more information, see Amazon Elastic Block Store and Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.

Public Method CreateSnapshotAsync(CreateSnapshotRequest, CancellationToken) Initiates the asynchronous execution of the CreateSnapshot operation.
Public Method CreateSpotDatafeedSubscription(CreateSpotDatafeedSubscriptionRequest) Creates a data feed for Spot instances, enabling you to view Spot instance usage logs. You can create one data feed per AWS account. For more information, see Spot Instance Data Feed in the Amazon Elastic Compute Cloud User Guide.
Public Method CreateSpotDatafeedSubscriptionAsync(CreateSpotDatafeedSubscriptionRequest, CancellationToken) Initiates the asynchronous execution of the CreateSpotDatafeedSubscription operation.
Public Method CreateSubnet(CreateSubnetRequest) Creates a subnet in an existing VPC.

When you create each subnet, you provide the VPC ID and the CIDR block you want for the subnet. After you create a subnet, you can't change its CIDR block. The subnet's CIDR block can be the same as the VPC's CIDR block (assuming you want only a single subnet in the VPC), or a subset of the VPC's CIDR block. If you create more than one subnet in a VPC, the subnets' CIDR blocks must not overlap. The smallest subnet (and VPC) you can create uses a /28 netmask (16 IP addresses), and the largest uses a /16 netmask (65,536 IP addresses).

AWS reserves both the first four and the last IP address in each subnet's CIDR block. They're not available for use.

If you add more than one subnet to a VPC, they're set up in a star topology with a logical router in the middle.

If you launch an instance in a VPC using an Amazon EBS-backed AMI, the IP address doesn't change if you stop and restart the instance (unlike a similar instance launched outside a VPC, which gets a new IP address when restarted). It's therefore possible to have a subnet with no running instances (they're all stopped), but no remaining IP addresses available.

For more information about subnets, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide.

Public Method CreateSubnetAsync(CreateSubnetRequest, CancellationToken) Initiates the asynchronous execution of the CreateSubnet operation.
Public Method CreateTags(CreateTagsRequest) Adds or overwrites one or more tags for the specified Amazon EC2 resource or resources. Each resource can have a maximum of 10 tags. Each tag consists of a key and optional value. Tag keys must be unique per resource.

For more information about tags, see Tagging Your Resources in the Amazon Elastic Compute Cloud User Guide.

Public Method CreateTagsAsync(CreateTagsRequest, CancellationToken) Initiates the asynchronous execution of the CreateTags operation.
Public Method CreateVolume(CreateVolumeRequest) Creates an EBS volume that can be attached to an instance in the same Availability Zone. The volume is created in the regional endpoint that you send the HTTP request to. For more information see Regions and Endpoints.

You can create a new empty volume or restore a volume from an EBS snapshot. Any AWS Marketplace product codes from the snapshot are propagated to the volume.

You can create encrypted volumes with the Encrypted parameter. Encrypted volumes may only be attached to instances that support Amazon EBS encryption. Volumes that are created from encrypted snapshots are also automatically encrypted. For more information, see Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide.

For more information, see Creating or Restoring an Amazon EBS Volume in the Amazon Elastic Compute Cloud User Guide.

Public Method CreateVolumeAsync(CreateVolumeRequest, CancellationToken) Initiates the asynchronous execution of the CreateVolume operation.
Public Method CreateVpc(CreateVpcRequest) Creates a VPC with the specified CIDR block.

The smallest VPC you can create uses a /28 netmask (16 IP addresses), and the largest uses a /16 netmask (65,536 IP addresses). To help you decide how big to make your VPC, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide.

By default, each instance you launch in the VPC has the default DHCP options, which includes only a default DNS server that we provide (AmazonProvidedDNS). For more information about DHCP options, see DHCP Options Sets in the Amazon Virtual Private Cloud User Guide.

Public Method CreateVpcAsync(CreateVpcRequest, CancellationToken) Initiates the asynchronous execution of the CreateVpc operation.
Public Method CreateVpcEndpoint(CreateVpcEndpointRequest) Creates a VPC endpoint for a specified AWS service. An endpoint enables you to create a private connection between your VPC and another AWS service in your account. You can specify an endpoint policy to attach to the endpoint that will control access to the service from your VPC. You can also specify the VPC route tables that use the endpoint.

Currently, only endpoints to Amazon S3 are supported.

Public Method CreateVpcEndpointAsync(CreateVpcEndpointRequest, CancellationToken) Initiates the asynchronous execution of the CreateVpcEndpoint operation.
Public Method CreateVpcPeeringConnection(CreateVpcPeeringConnectionRequest) Requests a VPC peering connection between two VPCs: a requester VPC that you own and a peer VPC with which to create the connection. The peer VPC can belong to another AWS account. The requester VPC and peer VPC cannot have overlapping CIDR blocks.

The owner of the peer VPC must accept the peering request to activate the peering connection. The VPC peering connection request expires after 7 days, after which it cannot be accepted or rejected.

A CreateVpcPeeringConnection request between VPCs with overlapping CIDR blocks results in the VPC peering connection having a status of failed.

Available snapshots include public snapshots available for any AWS account to launch, private snapshots that you own, and private snapshots owned by another AWS account but for which you've been given explicit create volume permissions.

The create volume permissions fall into the following categories:

  • public: The owner of the snapshot granted create volume permissions for the snapshot to the all group. All AWS accounts have create volume permissions for these snapshots.
  • explicit: The owner of the snapshot granted create volume permissions to a specific AWS account.
  • implicit: An AWS account has implicit create volume permissions for all snapshots it owns.

The list of snapshots returned can be modified by specifying snapshot IDs, snapshot owners, or AWS accounts with create volume permissions. If no options are specified, Amazon EC2 returns all snapshots for which you have create volume permissions.

If you specify one or more snapshot IDs, only snapshots that have the specified IDs are returned. If you specify an invalid snapshot ID, an error is returned. If you specify a snapshot ID for which you do not have access, it is not included in the returned results.

If you specify one or more snapshot owners, only snapshots from the specified owners and for which you have access are returned. The results can include the AWS account IDs of the specified owners, amazon for snapshots owned by Amazon, or self for snapshots that you own.

If you specify a list of restorable users, only snapshots with create snapshot permissions for those users are returned. You can specify AWS account IDs (if you own the snapshots), self for snapshots for which you own or have explicit permissions, or all for public snapshots.

If you are describing a long list of snapshots, you can paginate the output to make the list more manageable. The MaxResults parameter sets the maximum number of results returned in a single page. If the list of results exceeds your MaxResults value, then that number of results is returned along with a NextToken value that can be passed to a subsequent DescribeSnapshots request to retrieve the remaining results.

For more information about EBS snapshots, see Amazon EBS Snapshots in the Amazon Elastic Compute Cloud User Guide.

Public Method DescribeSnapshotsAsync(DescribeSnapshotsRequest, CancellationToken) Initiates the asynchronous execution of the DescribeSnapshots operation.

Public Method DescribeSpotFleetRequests(DescribeSpotFleetRequestsRequest) Describes your Spot fleet requests.
Public Method DescribeSpotFleetRequestsAsync(DescribeSpotFleetRequestsRequest, CancellationToken) Initiates the asynchronous execution of the DescribeSpotFleetRequests operation.
Public Method DescribeSpotInstanceRequests() Describes the Spot instance requests that belong to your account. Spot instances are instances that Amazon EC2 launches when the bid price that you specify exceeds the current Spot price. Amazon EC2 periodically sets the Spot price based on available Spot instance capacity and current Spot instance requests. For more information, see Spot Instance Requests in the Amazon Elastic Compute Cloud User Guide.

You can use DescribeSpotInstanceRequests to find a running Spot instance by examining the response. If the status of the Spot instance is fulfilled, the instance ID appears in the response and contains the identifier of the instance. Alternatively, you can use DescribeInstances with a filter to look for instances where the instance lifecycle is spot.

Public Method DescribeSpotInstanceRequests(DescribeSpotInstanceRequestsRequest) Describes the Spot instance requests that belong to your account.

If you are describing a long list of volumes, you can paginate the output to make the list more manageable. The MaxResults parameter sets the maximum number of results returned in a single page. If the list of results exceeds your MaxResults value, then that number of results is returned along with a NextToken value that can be passed to a subsequent DescribeVolumes request to retrieve the remaining results.

For more information about EBS volumes, see Amazon EBS Volumes in the Amazon Elastic Compute Cloud User Guide.

Public Method DescribeVolumes(DescribeVolumesRequest) Describes the specified EBS volumes.

If you are describing a long list of volumes, you can paginate the output to make the list more manageable. The MaxResults parameter sets the maximum number of results returned in a single page. If the list of results exceeds your MaxResults value, then that number of results is returned along with a NextToken value that can be passed to a subsequent DescribeVolumes request to retrieve the remaining results.

For more information about EBS volumes, see Amazon EBS Volumes in the Amazon Elastic Compute Cloud User Guide.

Public Method DescribeVolumesAsync(DescribeVolumesRequest, CancellationToken) Initiates the asynchronous execution of the DescribeVolumes operation.
Public Method DescribeVolumeStatus() Describes the status of the specified volumes. Volume status provides the result of the checks performed on your volumes to determine events that can impair the performance of your volumes. The performance of a volume can be affected if an issue occurs on the volume's underlying host. If the volume's underlying host experiences a power outage or system issue, after the system is restored, there could be data inconsistencies on the volume. Volume events notify you if this occurs. Volume actions notify you if any action needs to be taken in response to the event.

The DescribeVolumeStatus operation provides the following information about the specified volumes:

Status: Reflects the current status of the volume. The possible values are ok, impaired , warning, or insufficient-data. If all checks pass, the overall status of the volume is ok. If the check fails, the overall status is impaired. If the status is insufficient-data, then the checks may still be taking place on your volume at the time. We recommend that you retry the request. For more information on volume status, see Monitoring the Status of Your Volumes.

Events: Reflect the cause of a volume status and may require you to take action. For example, if your volume returns an impaired status, then the volume event might be potential-data-inconsistency. This means that your volume has been affected by an issue with the underlying host, has all I/O operations disabled, and may have inconsistent data.

Actions: Reflect the actions you may have to take in response to an event. For example, if the status of the volume is impaired and the volume event shows potential-data-inconsistency, then the action shows enable-volume-io. This means that you may want to enable the I/O operations for the volume by calling the EnableVolumeIO action and then check the volume for data consistency.

Volume status is based on the volume status checks, and does not reflect the volume state. Therefore, volume status does not indicate volumes in the error state (for example, when a volume is incapable of accepting I/O.)

Public Method DetachNetworkInterface(DetachNetworkInterfaceRequest) Detaches a network interface from an instance.
Public Method DetachNetworkInterfaceAsync(DetachNetworkInterfaceRequest, CancellationToken) Initiates the asynchronous execution of the DetachNetworkInterface operation.
Public Method DetachVolume(DetachVolumeRequest) Detaches an EBS volume from an instance. Make sure to unmount any file systems on the device within your operating system before detaching the volume. Failure to do so results in the volume being stuck in a busy state while detaching.

If an Amazon EBS volume is the root device of an instance, it can't be detached while the instance is running. To detach the root volume, stop the instance first.

When a volume with an AWS Marketplace product code is detached from an instance, the product code is no longer associated with the instance.

For more information, see Detaching an Amazon EBS Volume in the Amazon Elastic Compute Cloud User Guide.

Public Method DetachVolumeAsync(DetachVolumeRequest, CancellationToken) Initiates the asynchronous execution of the DetachVolume operation.
Public Method DetachVpnGateway(DetachVpnGatewayRequest) Detaches a virtual private gateway from a VPC. You do this if you're planning to turn off the VPC and not use it anymore. You can confirm a virtual private gateway has been completely detached from a VPC by describing the virtual private gateway (any attachments to the virtual private gateway are also described).

You must wait for the attachment's state to switch to detached before you can delete the VPC or attach a different VPC to the virtual private gateway.

Public Method DetachVpnGatewayAsync(DetachVpnGatewayRequest, CancellationToken) Initiates the asynchronous execution of the DetachVpnGateway operation.
Public Method DisableVgwRoutePropagation(DisableVgwRoutePropagationRequest) Disables a virtual private gateway (VGW) from propagating routes to a specified route table of a VPC.
Public Method DisableVgwRoutePropagationAsync(DisableVgwRoutePropagationRequest, CancellationToken) Initiates the asynchronous execution of the DisableVgwRoutePropagation operation.
Public Method DisableVpcClassicLink(DisableVpcClassicLinkRequest) Disables ClassicLink for a VPC. You cannot disable ClassicLink for a VPC that has EC2-Classic instances linked to it.
Public Method DisableVpcClassicLinkAsync(DisableVpcClassicLinkRequest, CancellationToken) Initiates the asynchronous execution of the DisableVpcClassicLink operation.
Public Method DisassociateAddress(DisassociateAddressRequest) Disassociates an Elastic IP address from the instance or network interface it's associated with.

An Elastic IP address is for use in either the EC2-Classic platform or in a VPC. For more information, see Elastic IP Addresses in the Amazon Elastic Compute Cloud User Guide.

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error.

Public Method DisassociateAddressAsync(DisassociateAddressRequest, CancellationToken) Initiates the asynchronous execution of the DisassociateAddress operation.
Public Method DisassociateRouteTable(DisassociateRouteTableRequest) Disassociates a subnet from a route table.

After you perform this action, the subnet no longer uses the routes in the route table. Instead, it uses the routes in the VPC's main route table. For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

Public Method DisassociateRouteTableAsync(DisassociateRouteTableRequest, CancellationToken) Initiates the asynchronous execution of the DisassociateRouteTable operation.

Public Method EnableVpcClassicLink(EnableVpcClassicLinkRequest) Enables a VPC for ClassicLink. You can then link EC2-Classic instances to your ClassicLink-enabled VPC to allow communication over private IP addresses. You cannot enable your VPC for ClassicLink if any of your VPC's route tables have existing routes for address ranges within the 10.0.0.0/8 IP address range, excluding local routes for VPCs in the 10.0.0.0/16 and 10.1.0.0/16 IP address ranges. For more information, see ClassicLink in the Amazon Elastic Compute Cloud User Guide.
Public Method EnableVpcClassicLinkAsync(EnableVpcClassicLinkRequest, CancellationToken) Initiates the asynchronous execution of the EnableVpcClassicLink operation.
Public Method GetConsoleOutput(GetConsoleOutputRequest) Gets the console output for the specified instance.

Instances do not have a physical monitor through which you can view their console output. They also lack physical controls that allow you to power up, reboot, or shut them down. To allow these actions, we provide them through the Amazon EC2 API and command line interface.

Instance console output is buffered and posted shortly after instance boot, reboot, and termination. Amazon EC2 preserves the most recent 64 KB output which is available for at least one hour after the most recent post.

For Linux instances, the instance console output displays the exact console output that would normally be displayed on a physical monitor attached to a computer. This output is buffered because the instance produces it and then posts it to a store where the instance's owner can retrieve it.

For Windows instances, the instance console output includes output from the EC2Config service.

Public Method GetConsoleOutputAsync(GetConsoleOutputRequest, CancellationToken) Initiates the asynchronous execution of the GetConsoleOutput operation.
Public Method GetPasswordData(GetPasswordDataRequest) Retrieves the encrypted administrator password for an instance running Windows.

The Windows password is generated at boot if the EC2Config service plugin, Ec2SetPassword, is enabled. This usually only happens the first time an AMI is launched, and then Ec2SetPassword is automatically disabled. The password is not generated for rebundled AMIs unless Ec2SetPassword is enabled before bundling.

The password is encrypted using the key pair that you specified when you launched the instance. You must provide the corresponding key pair file.

Password generation and encryption takes a few moments. We recommend that you wait up to 15 minutes after launching an instance before trying to retrieve the generated password.

Public Method GetPasswordDataAsync(GetPasswordDataRequest, CancellationToken) Initiates the asynchronous execution of the GetPasswordData operation.
Public Method ImportImage(ImportImageRequest) Import single or multi-volume disk images or EBS snapshots into an Amazon Machine Image (AMI).
Public Method ImportImageAsync(ImportImageRequest, CancellationToken) Initiates the asynchronous execution of the ImportImage operation.
Public Method ImportInstance(ImportInstanceRequest) Creates an import instance task using metadata from the specified disk image. ImportInstance only supports single-volume VMs. To import multi-volume VMs, use ImportImage. After importing the image, you then upload it using the ec2-import-volume command in the EC2 command line tools. For more information, see Using the Command Line Tools to Import Your Virtual Machine to Amazon EC2 in the Amazon Elastic Compute Cloud User Guide.
Public Method ImportInstanceAsync(ImportInstanceRequest, CancellationToken) Initiates the asynchronous execution of the ImportInstance operation.
Public Method ImportKeyPair(ImportKeyPairRequest) Imports the public key from an RSA key pair that you created with a third-party tool. Compare this with CreateKeyPair, in which AWS creates the key pair and gives the keys to you (AWS keeps a copy of the public key). With ImportKeyPair, you create the key pair and give AWS just the public key. The private key is never transferred between you and AWS.

For more information about key pairs, see Key Pairs in the Amazon Elastic Compute Cloud User Guide.

Public Method ImportKeyPairAsync(ImportKeyPairRequest, CancellationToken) Initiates the asynchronous execution of the ImportKeyPair operation.

For more information, see Modifying Reserved Instances in the Amazon Elastic Compute Cloud User Guide.

Public Method ModifyReservedInstancesAsync(ModifyReservedInstancesRequest, CancellationToken) Initiates the asynchronous execution of the ModifyReservedInstances operation.
Public Method ModifySnapshotAttribute(ModifySnapshotAttributeRequest) Adds or removes permission settings for the specified snapshot. You may add or remove specified AWS account IDs from a snapshot's list of create volume permissions, but you cannot do both in a single API call. If you need to both add and remove account IDs for a snapshot, you must use multiple API calls.

For more information on modifying snapshot permissions, see Sharing Snapshots in the Amazon Elastic Compute Cloud User Guide.

Snapshots with AWS Marketplace product codes cannot be made public.

Public Method ModifySnapshotAttributeAsync(ModifySnapshotAttributeRequest, CancellationToken) Initiates the asynchronous execution of the ModifySnapshotAttribute operation.

Public Method ModifySubnetAttributeAsync(ModifySubnetAttributeRequest, CancellationToken) Initiates the asynchronous execution of the ModifySubnetAttribute operation.
Public Method ModifyVolumeAttribute(ModifyVolumeAttributeRequest) Modifies a volume attribute.

By default, all I/O operations for the volume are suspended when the data on the volume is determined to be potentially inconsistent, to prevent undetectable, latent data corruption. The I/O access to the volume can be resumed by first enabling I/O access and then checking the data consistency on your volume.

You can change the default behavior to resume I/O operations. We recommend that you change this only for boot volumes or for volumes that are stateless or disposable.

Public Method ModifyVolumeAttributeAsync(ModifyVolumeAttributeRequest, CancellationToken) Initiates the asynchronous execution of the ModifyVolumeAttribute operation.
Public Method ModifyVpcAttribute(ModifyVpcAttributeRequest) Modifies the specified attribute of the specified VPC.
Public Method ModifyVpcAttributeAsync(ModifyVpcAttributeRequest, CancellationToken) Initiates the asynchronous execution of the ModifyVpcAttribute operation.

Public Method MoveAddressToVpc(MoveAddressToVpcRequest) Moves an Elastic IP address from the EC2-Classic platform to the EC2-VPC platform. The Elastic IP address must be allocated to your account, and it must not be associated with an instance. After the Elastic IP address is moved, it is no longer available for use in the EC2-Classic platform, unless you move it back using the RestoreAddressToClassic request. You cannot move an Elastic IP address that's allocated for use in the EC2-VPC platform to the EC2-Classic platform.
Public Method MoveAddressToVpcAsync(MoveAddressToVpcRequest, CancellationToken) Initiates the asynchronous execution of the MoveAddressToVpc operation.
Public Method PurchaseReservedInstancesOffering(PurchaseReservedInstancesOfferingRequest) Purchases a Reserved Instance for use with your account. With Amazon EC2 Reserved Instances, you obtain a capacity reservation for a certain instance configuration over a specified period of time and pay a lower hourly rate compared to on-Demand Instance pricing.

Use DescribeReservedInstancesOfferings to get a list of Reserved Instance offerings that match your specifications. After you've purchased a Reserved Instance, you can check for your new Reserved Instance with DescribeReservedInstances.

For more information, see Reserved Instances and Reserved Instance Marketplace in the Amazon Elastic Compute Cloud User Guide.

Public Method PurchaseReservedInstancesOfferingAsync(PurchaseReservedInstancesOfferingRequest, CancellationToken) Initiates the asynchronous execution of the PurchaseReservedInstancesOffering operation.
Public Method RebootInstances(RebootInstancesRequest) Requests a reboot of one or more instances. This operation is asynchronous; it only queues a request to reboot the specified instances. The operation succeeds if the instances are valid and belong to you. Requests to reboot terminated instances are ignored.

If a Linux/Unix instance does not cleanly shut down within four minutes, Amazon EC2 performs a hard reboot.

For more information about troubleshooting, see Getting Console Output and Rebooting Instances in the Amazon Elastic Compute Cloud User Guide.

Public Method RebootInstancesAsync(RebootInstancesRequest, CancellationToken) Initiates the asynchronous execution of the RebootInstances operation.
Public Method RegisterImage(RegisterImageRequest) Registers an AMI. When you're creating an AMI, this is the final step you must complete before you can launch an instance from the AMI. For more information about creating AMIs, see Creating Your Own AMIs in the Amazon Elastic Compute Cloud User Guide.

For Amazon EBS-backed instances, CreateImage creates and registers the AMI in a single request, so you don't have to register the AMI yourself.

You can also use RegisterImage to create an Amazon EBS-backed Linux AMI from a snapshot of a root device volume. For more information, see Launching an Instance from a Snapshot in the Amazon Elastic Compute Cloud User Guide.

Some Linux distributions, such as Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES), use the EC2 billingProduct code associated with an AMI to verify subscription status for package updates. Creating an AMI from an EBS snapshot does not maintain this billing code, and subsequent instances launched from such an AMI will not be able to connect to package update infrastructure.

Similarly, although you can create a Windows AMI from a snapshot, you can't successfully launch an instance from the AMI.

To create Windows AMIs or to create AMIs for Linux operating systems that must retain AMI billing codes to work properly, see CreateImage.

If needed, you can deregister an AMI at any time. Any modifications you make to an AMI backed by an instance store volume invalidates its registration. If you make changes to an image, deregister the previous image and register the new image.

You can't register an image where a secondary (non-root) snapshot has AWS Marketplace product codes.

Public Method RegisterImageAsync(RegisterImageRequest, CancellationToken) Initiates the asynchronous execution of the RegisterImage operation.
Public Method RejectVpcPeeringConnection(RejectVpcPeeringConnectionRequest) Rejects a VPC peering connection request. The VPC peering connection must be in the pending-acceptance state. Use the DescribeVpcPeeringConnections request to view your outstanding VPC peering connection requests. To delete an active VPC peering connection, or to delete a VPC peering connection request that you initiated, use DeleteVpcPeeringConnection.
Public Method RejectVpcPeeringConnectionAsync(RejectVpcPeeringConnectionRequest, CancellationToken) Initiates the asynchronous execution of the RejectVpcPeeringConnection operation.
Public Method ReleaseAddress(ReleaseAddressRequest) Releases the specified Elastic IP address.

After releasing an Elastic IP address, it is released to the IP address pool and might be unavailable to you. Be sure to update your DNS records and any servers or devices that communicate with the address. If you attempt to release an Elastic IP address that you already released, you'll get an AuthFailure error if the address is already allocated to another AWS account.

[EC2-Classic, default VPC] Releasing an Elastic IP address automatically disassociates it from any instance that it's associated with. To disassociate an Elastic IP address without releasing it, use DisassociateAddress.

[Nondefault VPC] You must use DisassociateAddress to disassociate the Elastic IP address before you try to release it. Otherwise, Amazon EC2 returns an error (InvalidIPAddress.InUse).

Public Method ReleaseAddressAsync(ReleaseAddressRequest, CancellationToken) Initiates the asynchronous execution of the ReleaseAddress operation.
Public Method ReplaceNetworkAclAssociation(ReplaceNetworkAclAssociationRequest) Changes which network ACL a subnet is associated with. By default when you create a subnet, it's automatically associated with the default network ACL. For more information about network ACLs, see Network ACLs in the Amazon Virtual Private Cloud User Guide.
Public Method ReplaceNetworkAclAssociationAsync(ReplaceNetworkAclAssociationRequest, CancellationToken) Initiates the asynchronous execution of the ReplaceNetworkAclAssociation operation.
Public Method ReplaceNetworkAclEntry(ReplaceNetworkAclEntryRequest) Replaces an entry (rule) in a network ACL. For more information about network ACLs, see Network ACLs in the Amazon Virtual Private Cloud User Guide.
Public Method ReplaceNetworkAclEntryAsync(ReplaceNetworkAclEntryRequest, CancellationToken) Initiates the asynchronous execution of the ReplaceNetworkAclEntry operation.
Public Method ReplaceRoute(ReplaceRouteRequest) Replaces an existing route within a route table in a VPC. You must provide only one of the following: Internet gateway or virtual private gateway, NAT instance, VPC peering connection, or network interface.

For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

Public Method ReplaceRouteAsync(ReplaceRouteRequest, CancellationToken) Initiates the asynchronous execution of the ReplaceRoute operation.
Public Method ReplaceRouteTableAssociation(ReplaceRouteTableAssociationRequest) Changes the route table associated with a given subnet in a VPC. After the operation completes, the subnet uses the routes in the new route table it's associated with. For more information about route tables, see Route Tables in the Amazon Virtual Private Cloud User Guide.

You can also use ReplaceRouteTableAssociation to change which table is the main route table in the VPC. You just specify the main route table's association ID and the route table to be the new main route table.

Public Method ReplaceRouteTableAssociationAsync(ReplaceRouteTableAssociationRequest, CancellationToken) Initiates the asynchronous execution of the ReplaceRouteTableAssociation operation.
Public Method ReportInstanceStatus(ReportInstanceStatusRequest) Submits feedback about the status of an instance. The instance must be in the running state. If your experience with the instance differs from the instance status returned by DescribeInstanceStatus, use ReportInstanceStatus to report your experience with the instance. Amazon EC2 collects this information to improve the accuracy of status checks.

Use of this action does not change the value returned by DescribeInstanceStatus.

Public Method ReportInstanceStatusAsync(ReportInstanceStatusRequest, CancellationToken) Initiates the asynchronous execution of the ReportInstanceStatus operation.
Public Method RequestSpotFleet(RequestSpotFleetRequest) Creates a Spot fleet request.

You can submit a single request that includes multiple launch specifications that vary by instance type, AMI, Availability Zone, or subnet.

By default, the Spot fleet requests Spot instances in the Spot pool where the price per unit is the lowest. Each launch specification can include its own instance weighting that reflects the value of the instance type to your application workload.

Alternatively, you can specify that the Spot fleet distribute the target capacity across the Spot pools included in its launch specifications. By ensuring that the Spot instances in your Spot fleet are in different Spot pools, you can improve the availability of your fleet.

For more information, see Spot Fleet Requests in the Amazon Elastic Compute Cloud User Guide.

Public Method RequestSpotFleetAsync(RequestSpotFleetRequest, CancellationToken) Initiates the asynchronous execution of the RequestSpotFleet operation.
Public Method RequestSpotInstances(RequestSpotInstancesRequest) Creates a Spot instance request. Spot instances are instances that Amazon EC2 launches when the bid price that you specify exceeds the current Spot price. Amazon EC2 periodically sets the Spot price based on available Spot Instance capacity and current Spot instance requests. For more information, see Spot Instance Requests in the Amazon Elastic Compute Cloud User Guide.
Public Method RequestSpotInstancesAsync(RequestSpotInstancesRequest, CancellationToken) Initiates the asynchronous execution of the RequestSpotInstances operation.
Public Method ResetImageAttribute(ResetImageAttributeRequest) Resets an attribute of an AMI to its default value.

The productCodes attribute can't be reset.

Public Method ResetImageAttributeAsync(ResetImageAttributeRequest, CancellationToken) Initiates the asynchronous execution of the ResetImageAttribute operation.
Public Method ResetInstanceAttribute(ResetInstanceAttributeRequest) Resets an attribute of an instance to its default value. To reset the kernel or ramdisk, the instance must be in a stopped state. To reset the SourceDestCheck, the instance can be either running or stopped.

The SourceDestCheck attribute controls whether source/destination checking is enabled. The default value is true, which means checking is enabled. This value must be false for a NAT instance to perform NAT. For more information, see NAT Instances in the Amazon Virtual Private Cloud User Guide.

Public Method ResetInstanceAttributeAsync(ResetInstanceAttributeRequest, CancellationToken) Initiates the asynchronous execution of the ResetInstanceAttribute operation.
Public Method ResetNetworkInterfaceAttribute(ResetNetworkInterfaceAttributeRequest) Resets a network interface attribute. You can specify only one attribute at a time.
Public Method ResetNetworkInterfaceAttributeAsync(ResetNetworkInterfaceAttributeRequest, CancellationToken) Initiates the asynchronous execution of the ResetNetworkInterfaceAttribute operation.
Public Method ResetSnapshotAttribute(ResetSnapshotAttributeRequest) Resets permission settings for the specified snapshot.

For more information on modifying snapshot permissions, see Sharing Snapshots in the Amazon Elastic Compute Cloud User Guide.

Public Method ResetSnapshotAttributeAsync(ResetSnapshotAttributeRequest, CancellationToken) Initiates the asynchronous execution of the ResetSnapshotAttribute operation.
Public Method RestoreAddressToClassic(RestoreAddressToClassicRequest) Restores an Elastic IP address that was previously moved to the EC2-VPC platform back to the EC2-Classic platform. You cannot move an Elastic IP address that was originally allocated for use in EC2-VPC. The Elastic IP address must not be associated with an instance or network interface.
Public Method RestoreAddressToClassicAsync(RestoreAddressToClassicRequest, CancellationToken) Initiates the asynchronous execution of the RestoreAddressToClassic operation.
Public Method RevokeSecurityGroupEgress(RevokeSecurityGroupEgressRequest) Removes one or more egress rules from a security group for EC2-VPC. The values that you specify in the revoke request (for example, ports) must match the existing rule's values for the rule to be revoked.

Each rule consists of the protocol and the CIDR range or source security group. For the TCP and UDP protocols, you must also specify the destination port or range of ports. For the ICMP protocol, you must also specify the ICMP type and code.

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

Public Method RevokeSecurityGroupEgressAsync(RevokeSecurityGroupEgressRequest, CancellationToken) Initiates the asynchronous execution of the RevokeSecurityGroupEgress operation.
Public Method RevokeSecurityGroupIngress(RevokeSecurityGroupIngressRequest) Removes one or more ingress rules from a security group. The values that you specify in the revoke request (for example, ports) must match the existing rule's values for the rule to be removed.

Each rule consists of the protocol and the CIDR range or source security group. For the TCP and UDP protocols, you must also specify the destination port or range of ports. For the ICMP protocol, you must also specify the ICMP type and code.

Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur.

Public Method RevokeSecurityGroupIngressAsync(RevokeSecurityGroupIngressRequest, CancellationToken) Initiates the asynchronous execution of the RevokeSecurityGroupIngress operation.
Public Method RunInstances(RunInstancesRequest) Launches the specified number of instances using an AMI for which you have permissions.

When you launch an instance, it enters the pending state. After the instance is ready for you, it enters the running state. To check the state of your instance, call DescribeInstances.

If you don't specify a security group when launching an instance, Amazon EC2 uses the default security group. For more information, see Security Groups in the Amazon Elastic Compute Cloud User Guide.

[EC2-VPC only accounts] If you don't specify a subnet in the request, we choose a default subnet from your default VPC for you.

[EC2-Classic accounts] If you're launching into EC2-Classic and you don't specify an Availability Zone, we choose one for you.

Linux instances have access to the public key of the key pair at boot. You can use this key to provide secure access to the instance. Amazon EC2 public images use this feature to provide secure access without passwords. For more information, see Key Pairs in the Amazon Elastic Compute Cloud User Guide.

You can provide optional user data when launching an instance. For more information, see Instance Metadata in the Amazon Elastic Compute Cloud User Guide.

If any of the AMIs have a product code attached for which the user has not subscribed, RunInstances fails.

T2 instance types can only be launched into a VPC. If you do not have a default VPC, or if you do not specify a subnet ID in the request, RunInstances fails.

For more information about troubleshooting, see What To Do If An Instance Immediately Terminates, and Troubleshooting Connecting to Your Instance in the Amazon Elastic Compute Cloud User Guide.

Public Method RunInstancesAsync(RunInstancesRequest, CancellationToken) Initiates the asynchronous execution of the RunInstances operation.
Public Method StartInstances(StartInstancesRequest) Starts an Amazon EBS-backed AMI that you've previously stopped.

Instances that use Amazon EBS volumes as their root devices can be quickly stopped and started. When an instance is stopped, the compute resources are released and you are not billed for hourly instance usage. However, your root partition Amazon EBS volume remains, continues to persist your data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time. Each time you transition an instance from stopped to started, Amazon EC2 charges a full instance hour, even if transitions happen multiple times within a single hour.

Before stopping an instance, make sure it is in a state from which it can be restarted. Stopping an instance does not preserve data stored in RAM.

Performing this operation on an instance that uses an instance store as its root device returns an error.

For more information, see Stopping Instances in the Amazon Elastic Compute Cloud User Guide.

Public Method StartInstancesAsync(StartInstancesRequest, CancellationToken) Initiates the asynchronous execution of the StartInstances operation.
Public Method StopInstances(StopInstancesRequest) Stops an Amazon EBS-backed instance. Each time you transition an instance from stopped to started, Amazon EC2 charges a full instance hour, even if transitions happen multiple times within a single hour.

You can't start or stop Spot Instances.

Instances that use Amazon EBS volumes as their root devices can be quickly stopped and started. When an instance is stopped, the compute resources are released and you are not billed for hourly instance usage. However, your root partition Amazon EBS volume remains, continues to persist your data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time.

Before stopping an instance, make sure it is in a state from which it can be restarted. Stopping an instance does not preserve data stored in RAM.

Performing this operation on an instance that uses an instance store as its root device returns an error.

You can stop, start, and terminate EBS-backed instances. You can only terminate instance store-backed instances. What happens to an instance differs if you stop it or terminate it. For example, when you stop an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, the root device and any other devices attached during the instance launch are automatically deleted. For more information about the differences between stopping and terminating instances, see Instance Lifecycle in the Amazon Elastic Compute Cloud User Guide.

For more information about troubleshooting, see Troubleshooting Stopping Your Instance in the Amazon Elastic Compute Cloud User Guide.

Public Method StopInstancesAsync(StopInstancesRequest, CancellationToken) Initiates the asynchronous execution of the StopInstances operation.
Public Method TerminateInstances(TerminateInstancesRequest) Shuts down one or more instances. This operation is idempotent; if you terminate an instance more than once, each call succeeds.

Terminated instances remain visible after termination (for approximately one hour).

By default, Amazon EC2 deletes all EBS volumes that were attached when the instance launched. Volumes attached after instance launch continue running.

You can stop, start, and terminate EBS-backed instances. You can only terminate instance store-backed instances. What happens to an instance differs if you stop it or terminate it. For example, when you stop an instance, the root device and any other devices attached to the instance persist. When you terminate an instance, any attached EBS volumes with the DeleteOnTermination block device mapping parameter set to true are automatically deleted. For more information about the differences between stopping and terminating instances, see Instance Lifecycle in the Amazon Elastic Compute Cloud User Guide.

For more information about troubleshooting, see Troubleshooting Terminating Your Instance in the Amazon Elastic Compute Cloud User Guide.

Public Method TerminateInstancesAsync(TerminateInstancesRequest, CancellationToken) Initiates the asynchronous execution of the TerminateInstances operation.
