Amazon Elastic File System
Cloud-based storage service
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, and encrypted file storage for use with both AWS cloud services and on-premises resources. Amazon EFS is built to be able to grow and shrink automatically as files are added and removed. Amazon EFS supports Network File System (NFS) versions 4.0 and 4.1 (NFSv4) protocol, and control access to files through Portable Operating System Interface (POSIX) permissions.
01Use 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.
02Data consistency
Amazon EFS provides open-after-close consistency semantics that applications expect from NFS.
03Availability
Amazon EFS is available in all the public AWS regions at least since December 2019.
