The Ceph object store remains a project in transition: The developers announced a new GUI, a new storage back end, and CephFS stability in the just released Ceph v10.2.x, Jewel.

When building cloud environments, you need more than just a scalable infrastructure; you also need a high-performance storage component. We look at Ceph, a distributed object store and filesystem that pairs well in the cloud with OpenStack.

We look into some everyday questions that administrators with Ceph clusters tend to ask: What do I do if a fire breaks out or I run out of space in the cluster?

We look at the new features in Ceph version 0.56, alias “Bobtail,” talk about who would benefit from CephX Ceph encryption, and show you how a Ceph Cluster can be used as a replacement for classic block storage in virtual environments.

In this second article on scalable storage in cloud environments, we cover the inner workings of RADOS and how to avoid pitfalls.
