> I get it, but at the same time that is also what you lost when you locked yourself in with a particular vendor.

What are other viable practical alternative solution(s)?

Storage adapter to talk S3 compatible to target, assuming you're not relying on vendor specific extensions or behavior (ie this).

Off the top of my head, Backblaze B2, Cloudflare R2, etc are S3 compatible, and Minio locally.

There are no vendor specific extensions or behavior here, are there? Isn't it just a different billing structure?

I used to run one on-prem from DDN. Another good one is Nutanix. There are many out there.

If you have a big use case and you really understand your needs, it's very doable.
