Ceph is a distributed storage solution. Together with RADOS (reliable autonomic distributed object store), it is an object store that can be distributed redundantly over any number of servers.
Ceph offers the user three types of storage: The object store, virtual block devices and CephFS, a distributed file system. The objects are stored in a replicated manner. Ceph can absorb the failure of any component and heal itself, that is, recover destroyed data from replicas on other storage media.
