**JuiceFS** is a high-performance [POSIX](https://en.wikipedia.org/wiki/POSIX) file system released under GNU Affero General Public License v3.0. It is specially optimized for the cloud-native environment. Using the JuiceFS to store data, the data itself will be persisted in object storage (e.g. Amazon S3), and the metadata corresponding to the data can be persisted in various database engines such as Redis, MySQL, and SQLite according to the needs of the scene.
