+# Ceph 
+Ceph is a clustered and distributed storage manager.
+
+Ceph uniquely delivers object, block, and file storage in one unified system.
+Ceph is highly reliable, easy to manage, and free. Ceph delivers extraordinary
+scalability–thousands of clients accessing petabytes to exabytes of data. A
+Ceph Node leverages commodity hardware and intelligent daemons, and a Ceph
+Storage Cluster accommodates large numbers of nodes, which communicate with
+each other to replicate and redistribute data dynamically.
+
+## Architecture
+The architecture of the Ceph cluster is explained on [the Architecture
+chapter of the upstream Ceph
+documentation](https://docs.ceph.com/en/latest/architecture/)
