EFS

Amazon EFS (Elastic File System)

  • Think of it like a shared network drive that many EC2s can access at the same time.

  • It automatically grows/shrinks as you add/remove files (no need to set size).

  • Good for shared storage, web apps, content management, big data, home directories.

👉 Example: If you have 10 EC2 servers running a website and they all need to read/write the same images or logs, they can all connect to EFS at once
