At the middle level, a Flumotion planet is implemented using one manager daemon and one or more worker daemons. Each of these is implemented as a process on a machine. These processes can each live on different machines.
The manager daemon is the process that controls everything else. After it gets started, it starts an internal bouncer component used to authenticate workers and components later on. Then it waits for incoming connections from workers. Then it can tell the workers to start components. Those new components will also log in to the manager.
