SAA-C03 Q582 · Compute

Question

A company runs an application that uses Docker containers in an on-premises data center. The application runs on a container host that stores persistent data in a volume on the host. The container instances use the stored persistent data. The company wants to move the application to a fully managed service because the company does not want to manage any servers or storage infrastructure. Which solution will meet these requirements?

Accepted Answer

The question has two critical requirements:

**Requirement 1: Fully managed service (no servers or storage infrastructure to manage)**
- AWS Fargate is a **serverless compute engine** for containers. You don't provision, configure, or manage any EC2 instances. AWS handles the underlying infrastructure entirely.
- Amazon EFS is a **fully managed file system** — no storage infrastructure to manage, no provisioning of disks, no capacity planning needed.

**Requirement 2: Persistent storage accessible by container instances**
- Amazon EFS provides shared, persistent file storage that can be mounted as a volume in Fargate tasks.
- EFS supports concurrent access from multiple containers, mirroring the on-premises pattern where container instances share persistent data from a host volume.
- ECS F
