AL2023 offers several improvements over Amazon Linux 2 (AL2). For example, AL2023 takes a security-by-default approach to help improve your security posture with preconfigured security policies, SELinux in permissive mode and IMDSv2 enabled by default, and the availability of kernel live patching. With deterministic upgrades through versioned repositories, you can lock to a specific version of the Amazon Linux package repository, giving you control over how and when you absorb updates. With this capability, you can adhere to operational best practices more efficiently by ensuring consistency between package versions and updates across your environment.

Amazon Linux 2023 is generally available in all AWS Regions, including the AWS GovCloud (US) and the China Regions. To learn more about Amazon Linux 2023, see the AWS documentation.
