AWS also offers scalable file storage to use with EC2 using the NFS protocol. In EFS, the storage capacity is elastic, therefore it grows and shrinks when you add or remove files, respectively.
You can use EFS with multiple EC2 instances as a common data source for the same point of time. All of them can concurrently access the EFS stored files.
We can use it with an on-premise server as well when we have a direct connection between the on-premise server and VPC.
