+=====================
+ Ceph Object Gateway
+=====================
+
+:term:`Ceph Object Gateway` is an object storage interface built on top of
+``librados`` to provide applications with a RESTful gateway to
+Ceph Storage Clusters. :term:`Ceph Object Storage` supports two interfaces:
+
+#. **S3-compatible:** Provides object storage functionality with an interface
+   that is compatible with a large subset of the Amazon S3 RESTful API.
+
+#. **Swift-compatible:** Provides object storage functionality with an interface
+   that is compatible with a large subset of the OpenStack Swift API.
+
+Ceph Object Storage uses the Ceph Object Gateway daemon (``radosgw``), which is
+an HTTP server for interacting with a Ceph Storage Cluster. Since it
+provides interfaces compatible with OpenStack Swift and Amazon S3, the Ceph
+Object Gateway has its own user management. Ceph Object Gateway can store data
+in the same Ceph Storage Cluster used to store data from Ceph Filesystem clients
+or Ceph Block Device clients. The S3 and Swift APIs share a common namespace, so
+you may write data with one API and retrieve it with the other.
