AWS – AWS announces availability of ECS Optimized Windows Server 2025 AMIs

Amazon Web Services (AWS) has introduced Amazon ECS Optimized Windows AMIs compatible with Windows Server 2025, offering two distinct platforms: 2025-Core and 2025-Full. These AMIs are specifically engineered to support Windows container deployments on Amazon ECS. Each AMI comes ready-to-use with essential components and optimizations tailored for running containerized workloads, streamlining the container deployment process.

Windows Server 2025 provides enhanced performance optimization and improved resource utilization compared to previous versions, allowing for more efficient container operations. It features advanced security capabilities, including better isolation between containers to prevent container escape attacks and stronger kernel boundaries between containers and host. Windows Server 2025 also introduces enhanced networking capabilities like network namespace isolation and better integration with the Host Netwroking Service (HNS) that enable faster container communication and reduced latency.

Customers can find and launch Windows ECS instances directly from the Amazon EC2 Console or through API or CLI commands. Windows ECS Optimized AMIs can be run with all available pricing options for windows ECS instances and are enabled across all Public, AWS GovCloud (US) and China Regions of AWS.
