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.
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 audit data, artifacts and data model objects.
