Minio aims to democratize cloud storage by building object storage in the open source community. It is a minimal object storage server written in Golang and licensed under Apache license v2. It is compatible with Amazon S3 APIs.

Minio Object Storage has three components:

  • Minio Server Application: developers can build their own cloud storage with Minio server.
  • Minio Client: A tool to copy or move large quantities of data across the cloud.
  • Minio Libraries: SDK for developers to enable cloud storage capability in their application. Currently Java, Node.js and Go languages are supported.

Minio follows a ‘minimalist’ design principle. It reduces all the complicated features of storage to essentially get, put and list.

Core of Minio’s innovation is a technology called Donut. It is a distributed erasure coded storage backend, similar to NetApp’s WAFL or Oracle ZFS. It uses rubberband erasure coding to compute variable erasure parity codes. Donut can withstand multiple server and disk failures. Server also performs continuous SHA512 checksum verification to detect silent data corruption.

Released date
As of Jun 17 2015:

  • Minio client and libraries are ready for public use
  • Minio server runs on developers laptop or on a standalone server.
  • Public Minio server is available for application development and

Next 6/12 months, the company will announce distributed storage capabilities and a browser based user/operator console. Minio will receive continuous updates as there is no concept of version numbers.
