But StatefulSets require storage...someplace. We're dealing with that exact issue right now. Our K8s cluster is not playing nice with a NetApp NAS. We are exploring other options such as local iscsi storage volumes ($$$) or an external state store db (slow).

The point is that with native HA, it doesn't have to be distributed storage. You can use locally attached SSDs or NVMe drives, which are straight forward to manage and fast.

  Importantly, they also have independent failure modes. I’ve never known a SAN to be within an order of magnitude of the advertised uptime — and some interesting failures have been caused by HA features. Local storage avoids whole classes of problem and has much greater aggregate performance if you can make it work for your app.
