Amazon EC2 now supports sharing Amazon Machine Images across AWS Organizations and Organizational Units

You can now share your Amazon Machine Images (AMIs) with AWS Organizations and Organizational Units (OUs). Previously, you could share AMIs only with specific AWS account IDs. To share AMIs with AWS Organizations, you had to explicitly manage sharing of AMIs with AWS accounts that were added to or removed from AWS Organizations. With this new feature, you no longer have to update your AMI permissions because of organizational changes. AMI sharing will be automatically synced when organizational changes occur. This feature helps you centrally manage and govern your AMIs as you grow and scale your AWS accounts.
