TP Monitor Architectures(Cont.) Many-server single-router model-multiple application server processes access a common database;clients communicate with the application through a single communication process that routes requests. Independent server processes for multiple applications Multithread server process Run on parallel or distributed database Many server many-router model-multiple processes communicate with clients. Client communication processes interact with router processes that route their requests to the appropriate server. Controller process starts up and supervises other processes.
