In AWS, what service is commonly used for container orchestration?

• A. Amazon ECS.
• B. Amazon Elastic Kubernetes Service (EKS).
• C. Amazon CloudFormation.
• D. AWS Lambda.

Answer: (B)

Container orchestration automates deploying, scaling, and managing many containers across a cluster. Kubernetes is the most widely used platform for this, because it oversees scheduling, rollouts, health checks, and networking so applications stay running as intended. In AWS, the managed way to run Kubernetes is Amazon Elastic Kubernetes Service. It handles the Kubernetes control plane across multiple availability zones, takes care of patching and upgrades, and integrates smoothly with AWS networking and security features like VPCs, IAM, and security groups. This lets you use standard Kubernetes tooling and APIs (kubectl, Helm, deployments) while benefiting from AWS reliability and integration. If you’re aiming for Kubernetes-based orchestration with broad ecosystem support and portability, EKS is the natural choice. While ECS also orchestrates containers within AWS, it’s a different, AWS-native approach and doesn’t provide the Kubernetes API compatibility you get with EKS.
