• Supported Operating Systems: For container instances, ECS supports Amazon Linux, Amazon Linux 2, Amazon Linux 2023, Bottlerocket, and Windows Server. Containers themselves can run various OS images.
• Latest Stable Version: As a managed service, AWS maintains the latest stable version. Users consume the latest features and API updates as they become available.
• End of Support Date: N/A for the ECS service itself, as it is continuously supported by AWS. However, specific underlying components like the ECS-optimized Amazon Linux 2 AMI will reach end-of-life on June 30, 2026. The classic Amazon ECS console reached its end-of-life on December 4, 2023.
• End of Life Date: N/A for the ECS service itself. Underlying AMIs have their own lifecycle.
• Auto-update Expiration Date: N/A. AWS manages updates for the service. Users are responsible for updating their container images and, if using EC2 launch type, the underlying EC2 instances.
• License Type: AWS Service Terms, typically a pay-as-you-go model based on resource consumption.
• Deployment Model: Cloud-based, fully managed container orchestration service. It supports two primary launch types: EC2 (where users manage the underlying EC2 instances) and Fargate (a serverless option where AWS manages the infrastructure). ECS Anywhere extends the control plane to on-premises servers or virtual machines.

Technical Requirements

• RAM: Varies significantly based on the chosen launch type (EC2 or Fargate) and task definition. For Fargate, users specify required memory per task (e.g., 0.5GB to 30GB). For EC2, it depends on the instance type selected.
• Processor: Varies significantly based on the chosen launch type (EC2 or Fargate) and task definition. For Fargate, users specify required vCPUs per task (e.g., 0.25 vCPU to 16 vCPU). For EC2, it depends on the instance type selected.
• Storage: Ephemeral storage is provided for Fargate tasks, encrypted by default with AWS-owned keys, with an option for customer-managed KMS keys. For EC2 launch types, storage depends on the EC2 instance's EBS volumes. Amazon EBS data volumes can be configured per task for standalone or service-managed tasks. Amazon EFS can be used for persistent shared storage across tasks.
• Display: Not applicable, as ECS is a headless container orchestration service.
• Ports: Container instances require specific ports for the ECS agent (e.g., 51678-51680). Docker daemon ports (e.g., 2375, 2376, 2377, 7946, 4789) may be relevant for EC2 launch types. Ephemeral port ranges (e.g., 32768-61000 or 49153-65535) are used for dynamic port mapping with load balancers.
• Operating System: For EC2 launch type, ECS-optimized AMIs based on Amazon Linux, Bottlerocket, or Windows Server are supported.

Analysis of Technical Requirements:

AWS ECS offers flexible technical requirements, primarily driven by the choice between EC2 and Fargate launch types. Fargate abstracts away the underlying infrastructure, allowing users to specify CPU and memory at the task level, simplifying resource management.
