Storage
Amazon EFS and Amazon FSx
Managed file-system choices: EFS provides elastic shared file storage for Linux workloads, while FSx provides managed file systems for specific engines and workload needs.
Key points
- Multiple compute resources can mount a shared file system.
- EFS uses the NFS protocol for Linux-oriented workloads.
- FSx families provide managed file systems such as Windows File Server, OpenZFS, and NetApp ONTAP; exact variants are recognition context, not a tuning target.
Best-known use cases
- Share files among Linux-based compute using EFS.
- Use a managed file system compatible with a named enterprise file-system requirement through FSx.
What candidates often confuse it with
- EFS and FSx are file storage; EBS is block storage and S3 is object storage.
- Recognize Amazon FSx as a managed file-system family; detailed FSx for Lustre design is outside the current exam scope.
Key Cloud Practitioner takeaway
Shared filesystem semantics point to EFS or a suitable FSx family, not S3 or EBS.
