Which technology, when used with Amazon ECS, enables you to run containers without managing servers or EC2 instances?

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

Answer: (B)

The ability being tested is running containers in a serverless way with a container orchestrator. When you use AWS Fargate with Amazon ECS, you don’t manage the underlying servers or EC2 instances. Instead, you define your container tasks with their resource needs (cpu and memory) and networking, and AWS provisions, scales, and maintains the compute fleet for those tasks. This shifts the operational burden away from managing EC2 instances to focusing on your containers and services, with you paying for the resources your tasks actually use (per second). In contrast, using ECS with the EC2 launch type requires you to manage the cluster's instances yourself. Lambda runs code in a function-as-a-service model rather than containers in ECS, and EKS relates to Kubernetes rather than ECS.
