What is MinIO?

MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. It is API compatible with Amazon S3 cloud storage service. It can handle unstructured data such as photos, videos, log files, backups, and container images with (currently) the maximum supported object size of 5TB.

MinIO storage stack has three major components: MinIO Server, MinIO Client (a.k.a. mc, which is a command-line client for the object and file management with any Amazon S3 compatible servers), and MinIO Client SDK that can be used by application developers to interact with any Amazon S3 compatible server.

MinIO cloud storage server is designed to be minimal and scalable. It is light enough to be bundled along with the application stack, similar to NodeJS, and Redis.

Designed for high performance, MinIO offers a suite of features that are specific to large enterprise deployments, these include erasure coding, bitrot protection, encryption/WORM, identity management, continuous replication, global federation, and multi-cloud deployments via gateway mode.

MinIO server is hardware agnostic, it can be installed on physical or virtual machines or launched as Docker containers and deployed on container orchestration platforms like Kubernetes. (Source:
