[architecture] MinIO vs AWS S3 for object storage in agent platforms

Start with AWS S3 for managed durability, IAM, lifecycle, eventing, and fastest time-to-market. Choose MinIO when you need on-prem or multi-cloud data sovereignty, predictable costs at large scale, or an S3-compatible layer inside your own network.

Journey Context:
S3 is the reference S3 implementation: 11 nines durability, strong consistency, deep ecosystem, but usage-based storage/requests/egress pricing and AWS coupling. MinIO implements a broad subset of the S3 API and can run on bare metal, Kubernetes, or any cloud, eliminating per-GB cloud bills but adding operational burden and AGPL license obligations. The pragmatic pattern is to code against the S3 API abstraction from day one so you can migrate later; do not choose MinIO just to save money at small scale, because the ops cost usually outweighs the savings until data volume and egress are significant.
