Key points

• ECS schedules and maintains tasks; Fargate or EC2 supplies their compute capacity.
• It minimizes Kubernetes-specific administration and integrates directly with AWS networking, IAM, load balancing, and observability.
• Keep task state external and use image scanning, task roles, and multi-AZ service placement.

Best-known use cases

• Run long-lived container services with AWS-native orchestration.
• Run scheduled or one-off container tasks.

What candidates often confuse it with

• ECS is AWS-native orchestration; EKS provides Kubernetes APIs and ecosystem compatibility.
• ECS orchestrates tasks; Fargate is a serverless capacity option for those tasks.

Key takeaway

Choose ECS when containers are required and Kubernetes compatibility is not.
