The following list describes common deployment scenarios where [[Platform_Team/Harmonic_Distribution|Harmonic Distribution]] might be useful. The final model might be an intermediate variant of them.
* [[Platform_Team/Harmonic_Distribution/Online_peers|Online peers]]<br>There is a master server located in the Internet in highly accessible place for any maintaining work. The main task is supporting users that are connected to the server all time.
* [[Platform_Team/Harmonic_Distribution/Online|Online school server]]<br>School server has Internet connectivity and serve it into local network where it can be used by clients.
* [[Platform_Team/Harmonic_Distribution/Sneakernet|Offline school server]]<br>When school server itself and clients it serves are in Internet-less environment with only one way to be synchronized with outer world, [[wikipedia:Sneakernet|sneakernet]].
* [[Platform_Team/Harmonic_Distribution/Software#Software_Map|base software]] updates,
