If you want hosted S3-compatible storage, you should be able to combine Backblaze B2, Wasabi, or Cloudflare R2 with any VPS provider from the bandwidth alliance:

That should alleviate egress costs. Bonus that storage is also way cheaper.

If your capacity needs aren't very high you can just store data on your web server in a directory

Pocketbase (also in a Dokku-powered container) on a Hetzner Cloud VPS with attached storage. Stupidly cheap, very reliable.

minIO can also be self hosted as an s3 alternative. Or host a database. Likely just depends on the type of storage you are looking for

I would guess GP was referring to self-hosting minio.

Good ol local disk
