Introducing EC2 AMI Tag Sharing: Share EC2 tags across AWS accounts
AWS introduces EC2 AMI Tag Sharing, allowing AMI owners to share tags with accounts that can access the image. Tags use the `ec2:SharedTag/` prefix and propagate automatically, with implications for ABAC policies and account governance.
Sharing AMI tags across accounts can simplify governance and eliminate custom tag-replication workflows for AWS users. Teams using ABAC policies need to account for how shared tags affect access controls.
