Ceph is the OG. Every now and then different attempts to replace it pop up, work well for some use cases, and then realise how hard the actual problem they are trying to solve is. Ceph always wins in the end.

Ceph solves the distributed consistent block storage problem very well. But I hardly ever need that problem solved, it's way more often that I need a distributed highly available blob storage, and Ceph makes the wrong tradeoffs for this task.

Ceph is fundamentally an object storage system. RBD (block devices) are built on top of that layer.
