| High Level Architecture |
| ======================= |
| |
| The following diagram shows the high-level relationship between the system components: |

| |
| 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** containers 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. |
