Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file system for use with AWS Cloud services and on-premise resources.

Amazon EFS is built to scale on demand to petabytes without disrupting applications. Amazon EFS:

  • Grows and shrinks automatically as files are added and removed.
  • Eliminates the need to provision.
  • Manages capacity to accommodate growth.

Amazon EFS has the following features:

  • A simple web services interface that allows you to create and configure file systems quickly and easily. The service manages all of the file storage infrastructure to avoid the complexity of deploying, patching, and maintaining complex file system configurations.
  • Support for the Network File System version 4 (NFSv4.1 and NFSv4.0) protocol so your applications and tools work seamlessly with Amazon EFS.
  • Support for multiple Amazon EC2 instances that can access an Amazon EFS file system (at the same time), providing a common data source for workloads and applications running on more than one instance or server.

Use the AWS public cloud integration to discover and collect metrics against the AWS service.
