Key points

• ECS schedules containerized ETL workers without requiring the team to operate Kubernetes APIs.
• Task definitions, task roles, networking, resource sizing, and service or job scaling remain workload decisions.

Best-known use cases

• Run containerized ETL workers without operating a Kubernetes control plane.
• Scale independent processing tasks from a standard container image.

What candidates often confuse it with

• ECS offers AWS-native container orchestration; EKS is appropriate when Kubernetes compatibility and cluster-level control are required.

Key takeaway

Choose ECS for containerized processing that does not require the Kubernetes ecosystem.
