Joplin Server vs S3

I was wondering if anyone would have insights regarding the usage of Joplin Server vs S3 for instance.

In terms of features, Joplin Server provides now some goodies such as share notes with other users on the same server.

Using Joplin Server also allows self hosting. That would be possible also with "S3" if Minio would be supported.

Obviously, once solution allows you having your data locally while the other (S3) is in the clould.

Setting up and maitaining Joplin Server will def. take more time than paying a little bit for some S3 storage.

I would love to hear your toughts and maybe some tests results if anyone compared those 2 options. Once (if ever) Minio is supported, the comparison will be even more interesting since both can run on premise.
