13. SDC – Current System Deployment Architecture
User Experience layer (Frontend Jetty Server)
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.
Application Layer (Backend Jetty Server)
Containers all the application logic for the SDC.
Catalog/Data Management Layer
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.
