Snapshots of course, have been and are a key technology when discussing data workloads because they enable backup/restore seamlessly, on-demand and in a split second. Even though volume snapshots are in the alpha stage, several storage providers already have integrations, including one that is very interesting, Ceph RDB.

In this article we will look at how to integrate Ceph RBD (Rados Block Device) with Kubernetes and OpenShift. Ceph is of course a scale-out software-defined storage system that provides block, file and object storage. It focuses primarily on cloud-storage use cases. Providing storage for Kubernetes and OpenShift is just one of many use cases that fit very well with Ceph.
