First off, I don't think there is anything wrong with MinIO closing down its open source. There are simply too many people globally who use open source without being willing to pay for it. I started testing various alternatives a few months ago, and I still believe RustFS will emerge as the winner after MinIO's exit. I evaluated Garage, SeaweedFS, Ceph, and RustFS. Here are my conclusions: 1. RustFS and SeaweedFS are…
MinIO was more for the "mini" use case (or more like "anything not large scale", with a very broad definition of large scale). Here "works out of the box" is paramount.
And Ceph is more for the maxi use case. Here in depth fine tuning, highly complex setups, distributed setups and similar are the norm. Hence out of the box small scale setup experience is bearly relevant.
So they really don't fill out the same space, even through their functionality overlaps.
