[architecture] MinIO vs AWS S3: when is a self-hosted S3-compatible store the right call?

Use MinIO for Kubernetes-native, multi-cloud, or on-premise object storage where data sovereignty and S3 API compatibility matter; use AWS S3 when you want global edge caching, lifecycle tiers, replication, and zero storage operations.

Journey Context:
MinIO is a high-performance S3-compatible object store that runs as a single binary or a Kubernetes cluster and supports erasure coding. It is not a full AWS S3 clone: features like Glacier, S3 Object Lambda, and CloudFront integration do not exist, and the server is dual-licensed under AGPL v3/commercial. S3 provides unmatched ecosystem breadth and pay-per-use economics, but data leaves your network and egress costs can dominate. The common mistake is self-hosting MinIO at small scale to 'save money' while paying more in ops time and hardware; conversely, another mistake is expecting MinIO to drop into every S3 workflow without checking feature parity. MinIO wins at scale, multi-cloud abstraction, and compliance boundaries.
