 * 1) Within a Ceph cluster, pools are made available in which objects can be stored and retrieved. Gateways (such as the Rados Gateway) and other applications can use this to keep their data in a highly available manner.
 * 2) A pool can be exposed as a file system. Each Ceph cluster can currently hold one file system which can be made accessible by Linux clients. This file system is POSIX compliant and can be used to build highly available NFS services (or directly use the mounted file system).
 * 3) Rados block devices are stored in the Ceph cluster and can be used to build highly available virtualized infrastructure (for instance virtual guest images on a highly available cluster).
