What is an AWS EFS?

AWS EFS stands for Elastic File System. It is much similar to NFS server, where NFS stands for Network File System. In EFS, multiple EC2 instances can connect to one shared server and each one the instance is synchronised. As you mount the NFS server to any Linux host locally, this is as same as local Linux NFS server.

Let’s say you have multiple EC2’s/Fargate running tasks which needs to share data, you can use EFS for the same without worrying about speed and reliability.
