Micro Series: AWS ECS and EKS Conceptual Comparison

ECS is generally more AWS-specific and has a simpler set of concepts, while EKS gives you the broader Kubernetes ecosystem and model.

The most useful mapping to remember is ECS Task Definition ≈ Pod specification, ECS Task ≈ Pod, ECS Service ≈ Deployment.

Just don't map ECS Service → Kubernetes Service despite the names, they serve different purposes.
