What mature implementations of S3 are there? MinIO that rugpulled the community, Garage that doesn’t even have proper setup scripts in their Docker containers and expect you to do the init manually, or Zenko cloud server that more or less got abandoned? I think there’s also SeaweedFS which might do better but I’m surprised at how shitty everything seems in this space - surely people aren’t being crazy and either storing their files on the FS directly to expose access to them through their app (hello directory traversal attacks) or storing them in relational DBs (hello wasted bandwidth and bloated backups).

The odd jank extends further, like Sonatype Nexus and some other software hardcodes AWS regions to choose from when configuring the storage even though your self-hosted implementation doesn’t have anything to do with AWS so you just have to come up with fake regions. If the cloud vendors each have to reimplement it because there is nothing as quality as PostgreSQL is for DBs, but for S3, then I’m hardly surprised at the state of things.
