+Configure The Gateway
+=====================
+
+Once you have installed the Ceph Object Gateway packages, the next step is
+to configure your Ceph Object Gateway. There are two approaches: 
+
+- **Simple:** A `simple`_ Ceph Object Gateway configuration implies that you 
+  are running a Ceph Object Storage service in a single data center. So you can
+  configure the Ceph Object Gateway without regard to regions and zones.
+
+- **Federated:** A `federated`_ Ceph Object Gateway configuration implies that
+  you are running a Ceph Object Storage service in a geographically distributed 
+  manner for fault tolerance and failover. This involves configuring your
+  Ceph Object Gateway instances with regions and zones.
+
+Choose the approach that best reflects your cluster.
