In one sentence
A managed container image registry integrated with ECS, EKS, IAM, scanning, and deployment workflows.
Key points
- ECR stores and versions container images; it does not run containers.
- ECS, EKS, or other runtimes pull images from repositories when starting workloads.
- IAM controls access, and image scanning and lifecycle policies support security and cleanup.
Exam takeaway
Remember the separation: ECR stores, ECS/EKS orchestrates, and EC2/Fargate runs.
