-_Couchbase Mobile_ brings the power of NoSQL to the edge.
-The combination of _Sync Gateway_ and _Couchbase Lite_ coupled with the power of _Couchbase Server_ provides fast, efficient bidirectional synchronization of data between the edge and the cloud.
-Enabling you to deploy your offline-first mobile and embedded applications with greater agility on premises or in any cloud.
+
+== How the pieces fit together
+
+Couchbase Mobile supports three deployment patterns.
+
+In a self-managed deployment, Couchbase Lite connects to a Sync Gateway that you deploy and operate, and Sync Gateway pushes data to a self-managed Couchbase Server.
+
+In a fully managed deployment, Couchbase Lite connects directly to Capella App Services, and App Services syncs data to your Capella Operational cluster.
+
+In a hybrid deployment, Couchbase Lite connects to a self-managed Sync Gateway, but that Sync Gateway points to a Capella Operational cluster instead of a self-managed Couchbase Server.
+
+App Services is Capella's managed version of Sync Gateway. It runs the same synchronization engine, hosted and operated by Capella. Feature parity between the two is common but not guaranteed, since some Sync Gateway features may not carry over to App Services, and App Services has features of its own.
+
+For resource-constrained environments, such as single-board computers or point-of-sale terminals, Couchbase Edge Server sits between Couchbase Lite devices and the cloud sync layer.
