Features (1)
  • EC2 exposes public SSM parameters in AMI metadata

    Amazon EC2 now surfaces the Systems Manager (SSM) Parameter Store parameters associated with public AMIs directly in the AMI metadata when describing a public AMI. This provides an easy way to discover and reference the latest AMI version for infrastructure configurations.

Enhancements (1)
  • Simplifies AMI updates

    Previously, finding the SSM parameter for a public AMI required manual searching. The new integration allows using the SSM parameter as an alias that always resolves to the latest AMI version, simplifying updates across infrastructure.

Notes (1)
  • Availability

    This capability is available to all customers at no additional cost in all AWS regions, including AWS China and AWS GovCloud regions.
