AWS customers have been using Amazon ECS and Amazon EKS to run and optimize their Microsoft Windows Server workloads. ECS and EKS-optimized Amazon Machine Images (AMIs) for Windows Server have traditionally leveraged Mirantis Container Runtime (formerly Docker Engine – Enterprise) as the default runtime framework. AWS has now migrated all the latest (September 2022) container-optimized Windows Server AMIs to use Docker Community Edition (CE). This change is to help customers avoid additional costs to get support, bug fixes and security patches for Mirantis Container Runtime with the Microsoft announcement to transfer support for Mirantis Container Runtime to Mirantis at the end of September 2022.
