The GenRocket consists of a Front End API and a Back End API.
The application (i.e. GenRocket) receives input from the client (i.e. user) through the Front End API. For example, if a user accesses the GenRocket API and uses an API method to remove a Domain from a Scenario, this input is received from the Front End API.
The Back End API processes information for the application (i.e. GenRocket). For example, once the input is received from the Front End API, the Back End API will complete the request based on the received input.
