How to Create & Configure EFS(Elastic File System) on Amazon Web Service(AWS).

Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed, elastic NFS file system for use with AWS Cloud services and on-premises resources. Amazon EFS is easy to use and offers a simple interface that allows you to create and configure file systems quickly and easily.

With Amazon EFS, you can create a file system, mount the file system on an Amazon EC2 instance, and then read and write data to and from your file system. You can mount an Amazon EFS file system in your virtual private cloud (VPC), through the Network File System versions 4.0 and 4.1 (NFSv4) protocol.
