## Minio [![Gitter](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/minio/minio?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)

Minio is a distributed object storage server written in Golang. Source is available under free software / open source [Apache license 2.0](./LICENSE). API compatible with Amazon S3 cloud storage service.


## Description

Micro services environment provisions one Minio server per application instance. Scalability is achieved through large number of smaller personalized instances. This version of the Minio binary is built using Filesystem storage backend for magnetic and solid state disks.

Minio currently implements two backends

  - Filesystem (FS) - is available and ready for general purpose use.
  - ErasureCoded (XL) - is work in progress and not ready for general purpose use.

## Minio Client

[Minio Client (mc)](https://github.com/minio/mc#minio-client-mc-) provides a modern alternative to Unix commands like ``ls``, ``cat``, ``cp``, ``sync``, and ``diff``. It supports POSIX compatible filesystems and Amazon S3 compatible cloud storage systems. It is entirely written in Golang.

## Amazon S3 Compatible Client Libraries

- [Java Library](https://github.com/minio/minio-java)
- [Nodejs Library](https://github.com/minio/minio-js)
