+=======================

+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 web pages, and all resources that 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* containes all the logic for the SDC.
+
+SDC uses two storage components: Elastic Search(ES) and Cassandra
+
+- *Elastic Search* is used to index the auditing data received from different operations in the SDC.
+
+ This information can then be analyzed with Kibana. The *Kibana server* enables statistical analysis of the operations done, according to the business logic.
+
+- *Cassandra* is used to store auditing data, artifacts and data model objects.
