+
+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.
