S3 is one of the most expensive platforms out there, however. Look at backblaze B2 for an example of just HOW expensive S3 is.

When i moved from S3 to DO, my bill went from hundreds to $20/mo. The only thing that changed was the hosting provider.

B2 is mostly S3-compatible, so if they add the same support for preconditions on writes as S3 and GCS, nothing prevents using it as a backend for GlassDB.
