AWS Cloud Map Cross-Account Service Discovery

AWS Cloud Map now supports cross-account service discovery through integration with AWS Resource Access Manager (AWS RAM) in AWS GovCloud (US) Regions. This enhancement allows you to manage and discover cloud resources across AWS accounts, including Amazon ECS tasks, Amazon EC2 instances, and Amazon DynamoDB tables. Sharing your AWS Cloud Map namespace via AWS RAM enables workloads in other accounts to discover and manage resources registered in that namespace, simplifying resource sharing, reducing duplication, and promoting consistent service discovery across environments for organizations with multi-account architectures.

What to do

  • Create a resource share in AWS RAM.
  • Add the namespaces you want to share.
  • Specify the principals (accounts, OUs, or the organization) that should have access.

This feature is available in the AWS GovCloud (US-East) and AWS GovCloud (US-West) Regions via the AWS Management Console, API, SDK, CLI, and CloudFormation. To learn more, please refer to the AWS Cloud Map documentation.
