3 Tier mode
Every kosmos/BOS application runs in 3 tier mode. The programmer has to do nothing in order to give this capability to the delivered application.
The executable kosmos.exe that exists in the server runs automatically as middle tier Application Server.
The executables kosmos.exe that exists on the client machines run automatically as Clients of the above Application Server.
The required infrastructure in order to communicate the Application Server with its Clients is to exist connectivity in TCP/IP (internet) between the machines.
