Amazon EC2 introduces AMI ancestry for complete AMI lineage visibility

Amazon EC2 now provides Amazon Machine Image (AMI) ancestry that enables you to trace the complete lineage of any AMI, from its immediate parent through each preceding generation back to the root AMI. This capability gives you complete transparency into where your AMIs originated and how they've been propagated across regions. Previously, tracking AMI lineage required manual processes, custom tagging strategies, and complex record-keeping across regions. This approach was error-prone and difficult to maintain at scale, especially when AMIs were copied across multiple regions. Now, with AMI ancestry, you have full visibility into the entire generational chain of any AMI in your environment. AMI ancestry addresses critical use cases such as tracking AMIs for compliance with internal policies, identifying all potentially vulnerable AMIs when security issues are discovered in the ancestral chain, and maintaining complete visibility of an AMI’s origin across regions. AMI ancestry can be accessed using the AWS CLI, SDKs, or Console. This capability is available at no additional cost in all AWS Regions, including AWS China and AWS GovCloud (US) Regions.
