    Falcon can run in 2 modes: 
    1. Distributed. In this case, Falcon prism is what user should use to perform CRUD operations
on entities and direct CRUD operations against Falcon Server should not be allowed.
    2. Embedded. In this case, there is no Prism server at all, there is just one instance
of Server and all CRUD operations should be allowed against server in this mode.
