EC2 exposes public AMI SSM parameters in metadata
🔍 Amazon EC2 now includes the AWS Systems Manager (SSM) Parameter Store names associated with public AMIs directly in the AMI metadata. When you describe a public AMI, the response shows the related public SSM parameter, enabling easier discovery and referencing. This feature simplifies using SSM parameter aliases that resolve to the latest AMI versions and is available in all AWS regions, including China and GovCloud, at no extra cost.
