Ceph, a free-software storage platform, scalable to the exabyte level, became a hot topic this year. In fact, now Ceph is so stable it is used by some of the largest companies and projects in the world, including Yahoo!, CERN, Bloomberg. Hostinger also joined this league of Ceph users, but in our own way.
We deployed our larger, better-performing cluster using not RadosGW or RBD, but the very fresh Ceph’s file system (CephFS).
Pretty hard. But not impossible
Ceph is pretty hard to deploy and tune to make most of your cluster. There are tools to make deploying Ceph easier: ansible version ansible-ceph, saltstack version deep-sea, chef version ceph-chef and, of course, ceph-deploy.
