What do you use self-hosted S3 for? I feel like all the use cases I can think of would be better served by a network attached file system.

A fair few things want blob object storage like S3. NFS does not scale to ridiculous levels horizontally or vertically. S3 does things like de-duplication and other funky tricks.

So if you want to use an app that needs S3 then you need to deploy S3 and not NFS.

I run a minio cluster (S3) for Veeam backups at work. I also run multiple NFS for Veeam and VMware datastores.

Tools for the job mate!

I use a self-hosted s3 compatible object storage for cheap storage of Android apks and logs. I do push various processed items to Digital Ocean Spaces, so having the ability to use rclone / the same functions for both is useful.

The article didn't load for me (HN hug of death) so I was confused too as are many others in this comment thread (and some have been downvoted for simply asking). Just use the correct terminology; if you're in tech you know there's no room or excuse for ambiguity.
