Until now, sharing was possible only for unencrypted AMIs. To distribute an encrypted AMI, you followed a multi-step process that resulted in an AMI copy in each account. Now, you can directly share AMIs encrypted with your Customer-Managed CMK across accounts and launch Amazon EC2 instances from the shared AMI. This simplifies your AMI distribution process and reduces the snapshot storage cost associated with maintaining multiple AMI copies across accounts.
