ONAP-level Architecture
^^^^^^^^^^^^^^^^^^^^^^^

Usecase-UI itself is an independent component in ONAP, which means it could be deployed as an ONAP-level component.

Usecase-UI Architecture
^^^^^^^^^^^^^^^^^^^

Take a deep dive into Usecase-UI, we could see it mainly consists of two modules, which are the UI module and Server module respectively. 

The UI module provides Graphical User Interface (GUI) for operators and end-users (e.g. LCM, Monitor).

The Server module is the logic part of Usecase-UI. This part analyzes NS files for LCM function and subscribes vnf alarm and performance data for monitor function.
