Access AWS Cloud Map using an interface endpoint (AWS PrivateLink) - AWS Cloud Map

Access AWS Cloud Map using an interface endpoint (AWS PrivateLink)

You can use AWS PrivateLink to create a private connection between your VPC and AWS Cloud Map. You can access AWS Cloud Map as if it were in your VPC, without the use of an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Instances in your VPC don't need public IP addresses to access AWS Cloud Map.

You establish this private connection by creating an interface endpoint, powered by AWS PrivateLink. We create an endpoint network interface in each subnet that you enable for the interface endpoint. These are requester-managed network interfaces that serve as the entry point for traffic destined for AWS Cloud Map.

For more information, see Access AWS services through AWS PrivateLink in the AWS PrivateLink Guide.

Considerations for AWS Cloud Map

Before you set up an interface endpoint for AWS Cloud Map, review Considerations in the AWS PrivateLink Guide.

If your Amazon VPC doesn’t have an internet gateway and your tasks use the awslogs log driver to send log information to CloudWatch Logs, you must create an interface VPC endpoint for CloudWatch Logs. For more information, see Using CloudWatch Logs with Interface VPC Endpoints in the Amazon CloudWatch Logs User Guide.

VPC endpoints don’t support AWS cross-Region requests. Ensure that you create your endpoint in the same Region where you plan to issue your API calls to AWS Cloud Map.

VPC endpoints only support Amazon-provided DNS through Amazon Route 53. If you want to use your own DNS, you can use conditional DNS forwarding. For more information, see DHCP Options Sets in the Amazon VPC User Guide.

The security group attached to the VPC endpoint must allow incoming connections on port 443 from the private subnet of the Amazon VPC.

Create an interface endpoint for AWS Cloud Map

You can create an interface endpoint for AWS Cloud Map using either the Amazon VPC console or the AWS Command Line Interface (AWS CLI). For more information, see Create an interface endpoint in the AWS PrivateLink Guide.

Create an interface endpoint for AWS Cloud Map using the following service names:


DiscoverInstances API won't be available over these two endpoints.


Create an interface endpoint for AWS Cloud Map data plane to access the DiscoverInstances API using the following service names:

You'll need to disable host prefix injection when you call DiscoverInstances with the regional or zonal VPCE DNS names for data plane endpoints. The AWS CLI and AWS SDKs prepend the service endpoint with various host prefixes when you call each API operation, which produces invalid URLS when you specify a VPC endpoint.

If you enable private DNS for the interface endpoint, you can make API requests to AWS Cloud Map using its default Regional DNS name. For example,

VPCE AWS PrivateLink connection is supported in any Region where AWS Cloud Map is supported; however, a customer needs to check which Availability Zones support VPCE before defining an endpoint. To find out which Availability Zones are supported with interface VPC endpoints in a Region, use the describe-vpc-endpoint-services command or use the AWS Management Console. For example, the following commands return the availability zones to which you can deploy an AWS Cloud Map interface VPC endpoints within the US East (Ohio) Region:

aws --region us-east-2 ec2 describe-vpc-endpoint-services --query 'ServiceDetails[?ServiceName==``].AvailabilityZones[]'
