## What it is
MinIO is a high-performance, S3-compatible object storage server written in Go, released under AGPLv3, with client SDKs (Go, Java, JS, Python), a CLI (mc), and a Kubernetes operator. The open-source community repository is no longer maintained; development has moved to the commercial AIStor editions, with the community edition available as source only.

## Use cases
- self-host s3 compatible object storage
- store ml training data and model artifacts
- replace amazon s3 in private cloud
- object storage backend for kubernetes workloads
- build data lake on commodity hardware
- test s3 integrations locally
- backup target for databases and applications

## When to choose
- you need an S3-compatible API on your own infrastructure
- you want high-throughput storage for AI/ML or analytics pipelines
- you need multi-cloud or on-premises object storage with a Kubernetes operator
- you want a lightweight local S3 substitute for development and testing

## When to avoid
- you need vendor support, prebuilt binaries, or guaranteed maintenance - the community edition is source-only and no longer maintained
- your project cannot comply with AGPLv3 obligations
- you need block or file storage rather than object storage
- you rely on long-term community security patches for the open-source edition

## Facets
