What is Amazon Elastic File System?
Amazon Elastic File system is an elastic NFS file system that provides a scalable, easy, and fully managed file system to AWS resources especially for EC2 and on-premises resources. The main reason for using the term Elastic is that you can expand or shrink your storage space without disturbing the application running on this file system. A simple web interface allows you to create and configure file systems with ease. AWS manages EFS infrastructure for you so that you can avoid the complexity of deploying, patching, and maintaining complex file system configurations always.
Amazon EFS supports the Network File System version 4 (NFSv4.1 and NFSv4.0) protocol, so the applications and tools that you use older versions of NFS can be supported on Amazon EFS. Another important feature Amazon EFS supports is accessing the file system from different EC2 instances or servers simultaneously, and hence can be used for cluster storage for supported applications and providing a common data source for workloads and applications running on more than one instance or server.
