EFS storage
EFS storage is managed, elastic network file storage provided by Amazon Elastic File System and shared among compute resources.
Amazon Web Services in Action, Third Edition: An in-depth guide to AWS
Amazon EFS is a managed elastic network file system that provides shared file storage accessible by multiple compute resources.
- How it is used
- Provides shared file storage for Linux EC2 instances, including load-balanced web servers and stateful applications.
- How deep it goes
- Works through filesystem creation, mount targets, mounting, file-sharing verification, throughput choices, monitoring, and backups.
- Examples
- Uses shared WordPress files, a two-instance home directory test, and Jenkins state stored at /var/lib/jenkins.
- What you can do after
- Operate/configure it by mounting one filesystem on multiple EC2 instances and choosing security, availability, throughput, and backup settings.
Effective Platform Engineering
Amazon EFS is a managed, elastic file storage service that provides shared, scalable file systems for compute workloads.
- How it is used
- Deploys shared, resilient file storage for EKS workloads and validates its storage class during platform testing.
- How deep it goes
- Explains operational differences and exercises provisioning, mounting, cross-pod writes, and cleanup without detailing EFS internals.
- Examples
- Uses a ReadWriteMany claim, two BusyBox pods, shared files, UTC timestamps, and Bats assertions for cross-pod access.
- What you can do after
- Diagnose storage-class health by verifying shared mounts and cross-pod read/write behavior in an EKS cluster.
