Amazon Elastic File System (Amazon EFS) is a cloud storage service provided by Amazon Web Services (AWS) designed to provide scalable, elastic, concurrent with some restrictions,[3] and encrypted[4] file storage for use with both AWS cloud services and on-premises resources.[5] Amazon EFS is built to be able to grow [6] and shrink automatically as files are added and removed. Amazon EFS supports Network File System (NFS) versions 4.0 and 4.1 (NFSv4) protocol,[7] and control access to files through Portable Operating System Interface (POSIX) permissions.[8]

Use cases

According to Amazon, use cases for this file system service typically include content repositories, development environments, web server farms, home directories and big data applications.[9]

Data consistency

Amazon EFS provides open-after-close consistency semantics that applications expect from NFS.[3]

Availability

Amazon EFS is available in all the public AWS regions at least since December 2019.[10]
