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. If you associate an Elastic IP address with an instance that has an existing Elastic IP address, the existing address is disassociated from the instance, but remains allocated to your account.

[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. You cannot associate an Elastic IP address with an instance or network interface that has an existing Elastic IP address.

This is an idempotent operation. If you perform the operation more than once, Amazon EC2 doesn't return an error, and you may be charged for each time the Elastic IP address is remapped to the same instance. For more information, see the Elastic IP Addresses section of Amazon EC2 Pricing.

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.

Initiates the asynchronous execution of the AssociateIamInstanceProfile 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.

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)

Public Method CancelSpotFleetRequests(CancelSpotFleetRequestsRequest)

Cancels the specified Spot fleet requests.

After you cancel a Spot fleet request, the Spot fleet launches no new Spot instances. You must specify whether the Spot fleet should also terminate its Spot instances. If you terminate the instances, the Spot fleet request enters the cancelled_terminating state. Otherwise, the Spot fleet request enters the cancelled_running state and the instances continue to run until they are interrupted or you terminate them manually.

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 must verify whether another user's instance is eligible for support.

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.

To copy an encrypted snapshot that has been shared from another account, you must have permissions for the CMK used to encrypt the snapshot.

Snapshots created by the CopySnapshot action have an arbitrary volume ID that should not be used for any purpose.

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 may 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 CreateDefaultVpc(CreateDefaultVpcRequest)

Creates a default VPC with a size /16 IPv4 CIDR block and a default subnet in each Availability Zone. For more information about the components of a default VPC, see Default VPC and Default Subnets in the Amazon Virtual Private Cloud User Guide. You cannot specify the components of the default VPC yourself.

You can create a default VPC if you deleted your previous default VPC. You cannot have more than one default VPC per region.

If your account supports EC2-Classic, you cannot use this action to create a default VPC in a region that supports EC2-Classic. If you want a default VPC in a region that supports EC2-Classic, see "I really want a default VPC for my existing EC2 account. Is that possible?" in the Default VPCs FAQ.

Public Method CreateDefaultVpcAsync(CreateDefaultVpcRequest, CancellationToken)

Initiates the asynchronous execution of the CreateDefaultVpc 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. If you want your instance to receive a custom DNS hostname as specified in domain-name, you must set domain-name-servers to a custom DNS server.

  • 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). This value is used to complete unqualified DNS hostnames. 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 CreateEgressOnlyInternetGateway(CreateEgressOnlyInternetGatewayRequest)

[IPv6 only] Creates an egress-only Internet gateway for your VPC. An egress-only Internet gateway is used to enable outbound communication over IPv6 from instances in your VPC to the Internet, and prevents hosts outside of your VPC from initiating an IPv6 connection with your instance.

Public Method CreateEgressOnlyInternetGatewayAsync(CreateEgressOnlyInternetGatewayRequest, CancellationToken)

Initiates the asynchronous execution of the CreateEgressOnlyInternetGateway 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 CreateFpgaImage(CreateFpgaImageRequest)

Creates an Amazon FPGA Image (AFI) from the specified design checkpoint (DCP).

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 CreateNatGateway(CreateNatGatewayRequest)

Creates a NAT gateway in the specified subnet. A NAT gateway can be used to enable instances in a private subnet to connect to the Internet. This action creates a network interface in the specified subnet with a private IP address from the IP address range of the subnet. For more information, see NAT Gateways in the Amazon Virtual Private Cloud User Guide.

Public Method CreateNatGatewayAsync(CreateNatGatewayRequest, CancellationToken)

Initiates the asynchronous execution of the CreateNatGateway 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.

Initiates the asynchronous execution of the CreatePlacementGroup operation.

Public Method CreateReservedInstancesListing(CreateReservedInstancesListingRequest)

Creates a listing for Amazon EC2 Standard Reserved Instances to be sold in the Reserved Instance Marketplace. You can submit one Standard Reserved Instance listing at a time. To get a list of your Standard Reserved Instances, you can use the DescribeReservedInstances operation.

Only Standard Reserved Instances with a capacity reservation can be sold in the Reserved Instance Marketplace. Convertible Reserved Instances and Standard Reserved Instances with a regional benefit cannot be sold.

The Reserved Instance Marketplace matches sellers who want to resell Standard 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 Standard 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 Standard Reserved Instances, and specify the upfront price to receive for them. Your Standard Reserved Instance listings then become available for purchase. To view the details of your Standard 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, NAT gateway, VPC peering connection, network interface, or egress-only Internet gateway.

When determining how to route traffic, we use the route with the most specific match. For example, traffic is destined for the IPv4 address 192.0.2.3, and the route table includes the following two IPv4 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 500 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)

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 IPv4 CIDR block you want for the subnet. After you create a subnet, you can't change its CIDR block. The size of the subnet's IPv4 CIDR block can be the same as a VPC's IPv4 CIDR block, or a subset of a VPC's IPv4 CIDR block. If you create more than one subnet in a VPC, the subnets' CIDR blocks must not overlap. The smallest IPv4 subnet (and VPC) you can create uses a /28 netmask (16 IPv4 addresses), and the largest uses a /16 netmask (65,536 IPv4 addresses).

If you've associated an IPv6 CIDR block with your VPC, you can create a subnet with an IPv6 CIDR block that uses a /64 prefix length.

AWS reserves both the first four and the last IPv4 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)

For more information about tags, see Tagging Your Resources in the Amazon Elastic Compute Cloud User Guide. For more information about creating IAM policies that control users' access to resources based on tags, see Supported Resource-Level Permissions for Amazon EC2 API Actions 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.

You can tag your volumes during creation. For more information, see Tagging Your Amazon EC2 Resources.

For more information, see Creating 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 IPv4 CIDR block. The smallest VPC you can create uses a /28 netmask (16 IPv4 addresses), and the largest uses a /16 netmask (65,536 IPv4 addresses). To help you decide how big to make your VPC, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide.

You can optionally request an Amazon-provided IPv6 CIDR block for the VPC. The IPv6 CIDR block uses a /56 prefix length, and is allocated from Amazon's pool of IPv6 addresses. You cannot choose the IPv6 range for your VPC.

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.

You can specify the instance tenancy value for the VPC when you create it. You can't change this value for the VPC after you create it. For more information, see Dedicated Instances in the Amazon Elastic Compute Cloud User Guide.

Public Method CreateVpcAsync(CreateVpcRequest, CancellationToken)

Initiates the asynchronous execution of the CreateVpc operation.

Public Method CreateVpcEndpoint(CreateVpcEndpointRequest)

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.

If you try to create a VPC peering connection between VPCs that have overlapping CIDR blocks, the VPC peering connection status goes to failed.

Public Method CreateVpcPeeringConnectionAsync(CreateVpcPeeringConnectionRequest, CancellationToken)

Initiates the asynchronous execution of the CreateVpcPeeringConnection operation.

Public Method CreateVpnConnection(CreateVpnConnectionRequest)

Creates a VPN connection between an existing virtual private gateway and a VPN customer gateway. The only supported connection type is ipsec.1.

The response includes information that you need to give to your network administrator to configure your customer gateway.

We strongly recommend that you use HTTPS when calling this operation because the response contains sensitive cryptographic information for configuring your customer gateway.

If you decide to shut down your VPN connection for any reason and later create a new VPN connection, you must reconfigure your customer gateway with the new information returned from this call.

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

Public Method DescribeVolumesModificationsAsync(DescribeVolumesModificationsRequest, CancellationToken)

Initiates the asynchronous execution of the DescribeVolumesModifications 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 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)

Public Method GetHostReservationPurchasePreviewAsync(GetHostReservationPurchasePreviewRequest, CancellationToken)

Initiates the asynchronous execution of the GetHostReservationPurchasePreview operation.

Public Method GetPasswordData(GetPasswordDataRequest)

Retrieves the encrypted administrator password for a running Windows instance.

The Windows password is generated at boot by the EC2Config service or EC2Launch scripts (Windows Server 2016 and later). This usually only happens the first time an instance is launched. For more information, see EC2Config and EC2Launch in the Amazon Elastic Compute Cloud User Guide.

For the EC2Config service, 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.

When you launch an instance, password generation and encryption may take a few minutes. If you try to retrieve the password before it's available, the output returns an empty string. We recommend that you wait up to 15 minutes after launching an instance before trying to retrieve the generated password.

The following resource types support longer IDs: instance | reservation | snapshot | volume. For more information, see Resource IDs in the Amazon Elastic Compute Cloud User Guide.

This setting applies to the principal specified in the request; it does not apply to the principal that makes the request.

Resources created with longer IDs are visible to all IAM roles and users, regardless of these settings and provided that they have permission to use the relevant Describe command for the resource type.

Public Method ModifyIdentityIdFormatAsync(ModifyIdentityIdFormatRequest, CancellationToken)

Initiates the asynchronous execution of the ModifyIdentityIdFormat operation.

Public Method ModifyIdFormat(ModifyIdFormatRequest)

Modifies the ID format for the specified resource on a per-region basis. You can specify that resources should receive longer IDs (17-character IDs) when they are created. The following resource types support longer IDs: instance | reservation | snapshot | volume.

This setting applies to the IAM user who makes the request; it does not apply to the entire AWS account. By default, an IAM user defaults to the same settings as the root user. If you're using this action as the root user, then these settings apply to the entire account, unless an IAM user explicitly overrides these settings for themselves. For more information, see Resource IDs in the Amazon Elastic Compute Cloud User Guide.

Resources created with longer IDs are visible to all IAM roles and users, regardless of these settings and provided that they have permission to use the relevant Describe command for the resource type.

Public Method ModifyIdFormatAsync(ModifyIdFormatRequest, CancellationToken)

Initiates the asynchronous execution of the ModifyIdFormat operation.

Public Method ModifyImageAttribute(ModifyImageAttributeRequest)

Modifies the specified attribute of the specified AMI. You can specify only one attribute at a time.

AWS Marketplace product codes cannot be modified. Images with an AWS Marketplace product code cannot be made public.

The SriovNetSupport enhanced networking attribute cannot be changed using this command. Instead, enable SriovNetSupport on an instance and create an AMI from the instance. This will result in an image with SriovNetSupport enabled.

Public Method ModifyImageAttributeAsync(ModifyImageAttributeRequest, CancellationToken)

Initiates the asynchronous execution of the ModifyImageAttribute operation.

Public Method ModifyInstanceAttribute(ModifyInstanceAttributeRequest)

Modifies the specified attribute of the specified instance. You can specify only one attribute at a time.

To modify some attributes, the instance must be stopped. For more information, see Modifying Attributes of a Stopped Instance in the Amazon Elastic Compute Cloud User Guide.

Public Method ModifyInstanceAttributeAsync(ModifyInstanceAttributeRequest, CancellationToken)

Initiates the asynchronous execution of the ModifyInstanceAttribute operation.

Public Method ModifyInstancePlacement(ModifyInstancePlacementRequest)

Set the instance affinity value for a specific stopped instance and modify the instance tenancy setting.

Instance affinity is disabled by default. When instance affinity is host and it is not associated with a specific Dedicated Host, the next time it is launched it will automatically be associated with the host it lands on. This relationship will persist if the instance is stopped/started, or rebooted.

You can modify the host ID associated with a stopped instance. If a stopped instance has a new host ID association, the instance will target that host when restarted.

You can modify the tenancy of a stopped instance with a tenancy of host or dedicated.

Affinity, hostID, and tenancy are not required parameters, but at least one of them must be specified in the request. Affinity and tenancy can be modified in the same request, but tenancy can only be modified on instances that are stopped.

Public Method ModifyInstancePlacementAsync(ModifyInstancePlacementRequest, CancellationToken)

Initiates the asynchronous execution of the ModifyInstancePlacement operation.

Public Method ModifyNetworkInterfaceAttribute(ModifyNetworkInterfaceAttributeRequest)

Modifies the specified network interface attribute. You can specify only one attribute at a time.

Initiates the asynchronous execution of the ModifyNetworkInterfaceAttribute operation.

Public Method ModifyReservedInstances(ModifyReservedInstancesRequest)

Modifies the Availability Zone, instance count, instance type, or network platform (EC2-Classic or EC2-VPC) of your Standard Reserved Instances. The Reserved Instances to be modified must be identical, except for Availability Zone, network platform, and instance type.

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.

Encrypted snapshots and snapshots with AWS Marketplace product codes cannot be made public. Snapshots encrypted with your default CMK cannot be shared with other accounts.

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

Public Method ModifySnapshotAttributeAsync(ModifySnapshotAttributeRequest, CancellationToken)

Initiates the asynchronous execution of the ModifySnapshotAttribute operation.

Public Method ModifySpotFleetRequest(ModifySpotFleetRequestRequest)

Modifies the specified Spot fleet request.

While the Spot fleet request is being modified, it is in the modifying state.

To scale up your Spot fleet, increase its target capacity. The Spot fleet launches the additional Spot instances according to the allocation strategy for the Spot fleet request. If the allocation strategy is lowestPrice, the Spot fleet launches instances using the Spot pool with the lowest price. If the allocation strategy is diversified, the Spot fleet distributes the instances across the Spot pools.

To scale down your Spot fleet, decrease its target capacity. First, the Spot fleet cancels any open bids that exceed the new target capacity. You can request that the Spot fleet terminate Spot instances until the size of the fleet no longer exceeds the new target capacity. If the allocation strategy is lowestPrice, the Spot fleet terminates the instances with the highest price per unit. If the allocation strategy is diversified, the Spot fleet terminates instances across the Spot pools. Alternatively, you can request that the Spot fleet keep the fleet at its current size, but not replace any Spot instances that are interrupted or that you terminate manually.

Public Method ModifySpotFleetRequestAsync(ModifySpotFleetRequestRequest, CancellationToken)

Initiates the asynchronous execution of the ModifySpotFleetRequest operation.

Public Method ModifySubnetAttribute(ModifySubnetAttributeRequest)

Modifies a subnet attribute. You can only modify one attribute at a time.

Public Method ModifySubnetAttributeAsync(ModifySubnetAttributeRequest, CancellationToken)

Initiates the asynchronous execution of the ModifySubnetAttribute operation.

Public Method ModifyVolume(ModifyVolumeRequest)

You can modify several parameters of an existing EBS volume, including volume size, volume type, and IOPS capacity. If your EBS volume is attached to a current-generation EC2 instance type, you may be able to apply these changes without stopping the instance or detaching the volume from it. For more information about modifying an EBS volume running Linux, see Modifying the Size, IOPS, or Type of an EBS Volume on Linux. For more information about modifying an EBS volume running Windows, see Modifying the Size, IOPS, or Type of an EBS Volume on Windows.

When you complete a resize operation on your volume, you need to extend the volume's file-system size to take advantage of the new storage capacity. For information about extending a Linux file system, see Extending a Linux File System. For information about extending a Windows file system, see Extending a Windows File System.

You can use CloudWatch Events to check the status of a modification to an EBS volume. For information about CloudWatch Events, see the Amazon CloudWatch Events User Guide. You can also track the status of a modification using the DescribeVolumesModifications API. For information about tracking status changes using either method, see Monitoring Volume Modifications.

With previous-generation instance types, resizing an EBS volume may require detaching and reattaching the volume or stopping and restarting the instance. For more information about modifying an EBS volume running Linux, see Modifying the Size, IOPS, or Type of an EBS Volume on Linux. For more information about modifying an EBS volume running Windows, see Modifying the Size, IOPS, or Type of an EBS Volume on Windows.

If you reach the maximum volume modification rate per volume limit, you will need to wait at least six hours before applying further modifications to the affected EBS volume.

Public Method ModifyVolumeAsync(ModifyVolumeRequest, CancellationToken)

Initiates the asynchronous execution of the ModifyVolume 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)

Public Method ModifyVpcEndpointAsync(ModifyVpcEndpointRequest, CancellationToken)

Initiates the asynchronous execution of the ModifyVpcEndpoint operation.

Public Method ModifyVpcPeeringConnectionOptions(ModifyVpcPeeringConnectionOptionsRequest)

Modifies the VPC peering connection options on one side of a VPC peering connection. You can do the following:

  • Enable/disable communication over the peering connection between an EC2-Classic instance that's linked to your VPC (using ClassicLink) and instances in the peer VPC.

  • Enable/disable communication over the peering connection between instances in your VPC and an EC2-Classic instance that's linked to the peer VPC.

  • Enable/disable a local VPC to resolve public DNS hostnames to private IP addresses when queried from instances in the peer VPC.

If the peered VPCs are in different accounts, each owner must initiate a separate request to modify the peering connection options, depending on whether their VPC was the requester or accepter for the VPC peering connection. If the peered VPCs are in the same account, you can modify the requester and accepter options in the same request. To confirm which VPC is the accepter and requester for a VPC peering connection, use the DescribeVpcPeeringConnections command.

Public Method ModifyVpcPeeringConnectionOptionsAsync(ModifyVpcPeeringConnectionOptionsRequest, CancellationToken)

Initiates the asynchronous execution of the ModifyVpcPeeringConnectionOptions operation.

Public Method MonitorInstances(MonitorInstancesRequest)

Enables detailed monitoring for a running instance. Otherwise, basic monitoring is enabled. For more information, see Monitoring Your Instances and Volumes in the Amazon Elastic Compute Cloud User Guide.

To disable detailed monitoring, see .

Public Method MonitorInstancesAsync(MonitorInstancesRequest, CancellationToken)

Initiates the asynchronous execution of the MonitorInstances 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 for more than 24 hours, 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 was originally 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 PurchaseHostReservation(PurchaseHostReservationRequest)

Purchase a reservation with configurations that match those of your Dedicated Host. You must have active Dedicated Hosts in your account before you purchase a reservation. This action results in the specified reservation being purchased and charged to your account.

Public Method PurchaseHostReservationAsync(PurchaseHostReservationRequest, CancellationToken)

Initiates the asynchronous execution of the PurchaseHostReservation operation.

Public Method PurchaseReservedInstancesOffering(PurchaseReservedInstancesOfferingRequest)

Purchases a Reserved Instance for use with your account. With Reserved Instances, you 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 PurchaseScheduledInstances(PurchaseScheduledInstancesRequest)

Purchases one or more Scheduled Instances with the specified schedule.

Scheduled Instances enable you to purchase Amazon EC2 compute capacity by the hour for a one-year term. Before you can purchase a Scheduled Instance, you must call DescribeScheduledInstanceAvailability to check for available schedules and obtain a purchase token. After you purchase a Scheduled Instance, you must call RunScheduledInstances during each scheduled time period.

After you purchase a Scheduled Instance, you can't cancel, modify, or resell your purchase.

Public Method PurchaseScheduledInstancesAsync(PurchaseScheduledInstancesRequest, CancellationToken)

Initiates the asynchronous execution of the PurchaseScheduledInstances 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 an 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. You specify the snapshot using the block device mapping. For more information, see Launching a Linux Instance from a Backup in the Amazon Elastic Compute Cloud User Guide.

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

Some Linux distributions, such as Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES), use the EC2 billing product code associated with an AMI to verify the 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. To create an AMI that must retain billing codes, 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.

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.

[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 can release it. Otherwise, Amazon EC2 returns an error (InvalidIPAddress.InUse).

After releasing an Elastic IP address, it is released to the IP address pool. 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-VPC] After you release an Elastic IP address for use in a VPC, you might be able to recover it. For more information, see AllocateAddress.

Public Method ReleaseAddressAsync(ReleaseAddressRequest, CancellationToken)

Initiates the asynchronous execution of the ReleaseAddress operation.

Public Method ReleaseHosts(ReleaseHostsRequest)

When you no longer want to use an On-Demand Dedicated Host it can be released. On-Demand billing is stopped and the host goes into released state. The host ID of Dedicated Hosts that have been released can no longer be specified in another request, e.g., ModifyHosts. You must stop or terminate all instances on a host before it can be released.

When Dedicated Hosts are released, it make take some time for them to stop counting toward your limit and you may receive capacity errors when trying to allocate new Dedicated hosts. Try waiting a few minutes, and then try again.

Released hosts will still appear in a DescribeHosts response.

Public Method ReleaseHostsAsync(ReleaseHostsRequest, CancellationToken)

Initiates the asynchronous execution of the ReleaseHosts operation.

Public Method ReplaceIamInstanceProfileAssociation(ReplaceIamInstanceProfileAssociationRequest)

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, NAT gateway, VPC peering connection, network interface, or egress-only Internet gateway.

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.

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)

[EC2-VPC only] Removes one or more egress rules from a security group for EC2-VPC. This action doesn't apply to security groups for use in EC2-Classic. To remove a rule, the values that you specify (for example, ports) must match the existing rule's values exactly.

Each rule consists of the protocol and the IPv4 or IPv6 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. If the security group rule has a description, you do not have to specify the description to revoke the rule.

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. To remove a rule, the values that you specify (for example, ports) must match the existing rule's values exactly.

[EC2-Classic security groups only] If the values you specify do not match the existing rule's values, no error is returned. Use DescribeSecurityGroups to verify that the rule has been 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. If the security group rule has a description, you do not have to specify the description to revoke the rule.

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.

You can specify a number of options, or leave the default options. The following rules apply:

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

  • [EC2-Classic] If don't specify an Availability Zone, we choose one for you.

  • Some instance types must be launched into a VPC. If you do not have a default VPC, or if you do not specify a subnet ID, the request fails. For more information, see Instance Types Available Only in a VPC.

  • [EC2-VPC] All instances have a network interface with a primary private IPv4 address. If you don't specify this address, we choose one from the IPv4 range of your subnet.

  • Not all instance types support IPv6 addresses. For more information, see Instance Types.

  • If you don't specify a security group ID, we use the default security group. For more information, see Security Groups.

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

To ensure faster instance launches, break up large requests into smaller batches. For example, create five separate launch requests for 100 instances each instead of one launch request for 500 instances.

An instance is ready for you to use when it's in the running state. You can check the state of your instance using DescribeInstances. You can tag instances and EBS volumes during launch, after launch, or both. For more information, see CreateTags and Tagging Your Amazon EC2 Resources.

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.

For 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 RunScheduledInstances(RunScheduledInstancesRequest)

Launches the specified Scheduled Instances.

Before you can launch a Scheduled Instance, you must purchase it and obtain an identifier using PurchaseScheduledInstances.

You must launch a Scheduled Instance during its scheduled time period. You can't stop or reboot a Scheduled Instance, but you can terminate it as needed. If you terminate a Scheduled Instance before the current scheduled time period ends, you can launch it again after a few minutes. For more information, see Scheduled Instances in the Amazon Elastic Compute Cloud User Guide.

Public Method RunScheduledInstancesAsync(RunScheduledInstancesRequest, CancellationToken)

Initiates the asynchronous execution of the RunScheduledInstances operation.

Public Method StartInstances(StartInstancesRequest)

Starts an Amazon EBS-backed instance 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 instance usage. However, your root partition Amazon EBS volume remains and continues to persist your data, and you are charged for Amazon EBS volume usage. You can restart your instance at any time. Every time you start your Windows instance, Amazon EC2 charges you for a full instance hour. If you stop and restart your Windows instance, a new instance hour begins and Amazon EC2 charges you for another full instance hour even if you are still within the same 60-minute period when it was stopped. Every time you start your Linux instance, Amazon EC2 charges a one-minute minimum for instance usage, and thereafter charges per second for instance usage.

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.

We don't charge usage for a stopped instance, or data transfer fees; however, your root partition Amazon EBS volume remains and continues to persist your data, and you are charged for Amazon EBS volume usage. Every time you start your Windows instance, Amazon EC2 charges you for a full instance hour. If you stop and restart your Windows instance, a new instance hour begins and Amazon EC2 charges you for another full instance hour even if you are still within the same 60-minute period when it was stopped. Every time you start your Linux instance, Amazon EC2 charges a one-minute minimum for instance usage, and thereafter charges per second for instance usage.

You can't start or stop Spot Instances, and you can't stop instance store-backed instances.

When you stop an instance, we shut it down. 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.

Stopping an instance is different to rebooting or terminating 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 rebooting, stopping, and terminating instances, see Instance Lifecycle in the Amazon Elastic Compute Cloud User Guide.

When you stop an instance, we attempt to shut it down forcibly after a short while. If your instance appears stuck in the stopping state after a period of time, there may be an issue with the underlying host computer. For more information, 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.

If you specify multiple instances and the request fails (for example, because of a single incorrect instance ID), none of the instances are terminated.

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.
