Customers can now manage the lifecycle of their custom Amazon Machine Images (AMIs) and Container images created on EC2 Image Builder. Customers can save costs by deleting unused images that accumulate storage charges on AWS. You no longer have to keep track of their custom images distributed across AWS accounts and AWS regions, and manually retire them as the images become outdated. With this launch, we provide customers an automated way to identify and remove outdated images, avoiding accidental usage of those images.
