This new feature lets AMI owners explicitly define allowed and disallowed instance types, preventing failed launches due to incompatibility. Launch attempts on unsupported types are automatically blocked, proactively reducing operational issues.

By default, AMIs remain launchable across instance types unless restrictions are set, preserving existing behavior. Availability across all AWS Regions at no cost allows users to safeguard workloads by ensuring AMIs run only on tested, supported instances.
