[architecture] MinIO vs AWS S3 for object storage in a multi-cloud or on-prem deployment

Choose MinIO when egress/ingress costs dominate, you need data sovereignty, or you want S3-compatible storage on private cloud/bare metal; choose S3 when you need global replication, managed lifecycle, compliance certifications, and serverless integrations without hiring storage SREs. Treat MinIO as a storage layer, not a full AWS ecosystem replacement—plan for backups, erasure coding, identity federation, and observability yourself.

Journey Context:
AWS S3 is the reference object store with eleven-nines durability, cross-region replication, and deep integration, but per-request and egress pricing can explode with AI/ML workloads or large media. MinIO provides a high-performance, S3-compatible server \(AGPL v3\) that can run anywhere and avoids cloud egress, but you own scaling, upgrades, drive failures, and security patches. Common mistakes: assuming MinIO magically replicates S3's global redundancy on a single node, or ignoring the AGPL license implications when embedding it. For agents building apps, the decision hinges on whether object storage is a cost center \(self-host\) or a utility \(managed S3\).
