HAQM Elastic Container Service (HAQM ECS) today announced the public preview of the HAQM ECS-optimized HAQM Linux 2022 HAQM Machine Image (AMI). HAQM Linux 2022 (AL2022) is the next generation of HAQM Linux from HAQM Web Services (AWS) that is designed to provide a secure, stable, and high-performance execution environment to develop and run your cloud applications. Starting with AL2022, a new HAQM Linux major version will be available every two years and each major version will be supported for five years. HAQM ECS will publish HAQM ECS-optimized AMIs to support the same 2-year release and 5-year support cycle for every new major HAQM Linux version. The two-year major release cycle helps you keep your software up-to-date while the five year support commitment for each major release gives you the stability you need to manage long project lifecycles.
AL2022 is based on the Fedora project and provides frequent and flexible quarterly updates. AL2022 also locks to a specific version of the HAQM Linux package repository, which gives you control over how and when you absorb updates. In addition, AL2022 also comes with Security-Enhanced Linux (SELinux) policies for additional isolation. Furthermore, the HAQM ECS-optimized AL2022 AMI now uses cgroupsV2 as the default kernel setting for managing Task and container resources, which enables improved memory management.
The HAQM ECS-optimized AL2022 AMI is now available in preview in all commercial regions.
