 SDC Architecture
 ================
 
-SDC As Part of ONAP
-===================
+Please refer to the Guilin Architecture review page for SDC, to get a full picture of SDC and its relationships within ONAP

-
-High Level Architecture
-=======================
-
-The following diagram shows the high-level relationship between the system components:
-
-.. image:: images/High_Level_Architecture_SDC.png
-
-The SDC architecture uses the Jetty server as an application server.
-
-- The **Jetty front end**:
-   - supplies the static content of the web pages and all the resources that are required by the GUI
-   - serves as a proxy for the REST API requests coming from the GUI
-   
-  Every request originating from the GUI is passed to the Jetty front-end server before it is executed.
-
-- The **Jetty back end** contains all the logic for the SDC.
-
-- **Cassandra** is used to store audit data, artifacts and data model objects.

 Installation Guides
 ===================
-In Beijing SDC supports two deployment method Heat based deployment and OOM based deployment.
+In Guilin SDC is deployed through OOM based deployment.
 more information is available in the OOM and in the demo projects.
 
-For local deployment SDC offers two options:
-
-- `Deploying SDC on a Linux VM for Development <https://wiki.onap.org/display/DW/Deploying+SDC+on+a+Linux+VM+for+Development>`_
-- `Using Vagrant-Onap for local deployment of SDC project <https://wiki.onap.org/display/DW/Deploying+SDC+on+a+Linux+VM+for+Development>`_
+For local deployment SDC offers specific Maven Profiles (START-SDC and STOP-SDC)
