Chapter 10. STEP 10: Lobby Applications > Lobby Application Overview

Lobby Application Overview

Lobby applications, like the Subscriber application introduced in Chapter 9, “STEP 9: Controller and Subscriber Applications,” also maintain multiple user interfaces. The principle difference is that all user interfaces are public. A typical implementation is the chat room that contains multiple “rooms” for users to interact. You could also use instances to provide additional collaborative experiences such as multiple classrooms, meeting rooms, or other “creative” endeavors.

Network gaming is an excellent example to illustrate the concept. Let's say you build a game that can handle four players. A Lobby interface (shown in Figure 10.1) allows users to invite other users to join a game. Game play does not interact with other game plays concurrently running.
