EC2 adds watermarks to AMIs for governance

What's new

• Amazon EC2 introduces AMI watermarks for private AMIs.
• Watermarks embed metadata like AMI ID, owner ID, region, and creation timestamps.
• Watermarks persist across AMI copies, region changes, and instance launches.
• Watermarks are visible when AMIs are shared across accounts.

Why it matters

This feature provides a mechanism for tracking AMI lineage and enforcing compliance. Previously, managing AMI provenance across multiple accounts and regions required manual tracking or custom tooling. AMI watermarks automate this by embedding immutable metadata. This is particularly relevant for organizations with strict compliance requirements or those operating in regulated industries, where knowing the origin and approved status of an AMI is critical. The integration with Allowed AMIs and Declarative Policies allows for centralized governance, restricting deployments to only authorized images.

How to use it

Watermarks can be added to private AMIs via the AWS Management Console, AWS CLI, or SDKs. They can also be integrated into AMI build pipelines using EC2 Image Builder. AMI watermarks are available at no additional cost in all AWS regions. Bottom line: EC2 AMI watermarks offer automated provenance tracking and governance enforcement for private images.
