Versity S3 Gateway

Judgement

What it is

Building block

What it does

A gateway that serves an existing POSIX filesystem, or other backends, through the S3 API so S3 clients can read and write files where they already are.

Adopt it when

You have data on a filesystem or HPC storage and want S3 access to it without migrating to an object store.

Watch out

S3 features beyond the basics depend on what the backend filesystem supports.
