photon loadbalancing on azure

cindyb2087

In azure, what happens if a master server is rebooted?
will all the game servers be down?
Will any new users be able to connect and play games during the time master server is down?

If a game server is rebooted, will we lose all the games going on that machine?

Azure sends an event with a timeout of 5 mins when a machine is about to be rebooted. Is there a way to stop the master server from sending new games to gameserver once that event is received on gameserver? This will help in saving gamedata for existing games and not start any new games till reboot happen and thus minimize gamesesssions lost.

The gameservers will reconnect once the master is available again.
And resync the lists of games.

no - games running on the game servers will stay up and clients stay connected

no - they will when the master is up again. Currently we don't have fail-over support. We are working on it.

Yes, currently you have to implement one part your self.
- inform the gameserver when the photon worker role receives the event (per file for instance)
- in the Photon.Loadbalancing.OutgoingServerPeer set GameApplication.Instance.WorkloadController.ServerState = ServerState.OutOfRotation
- and call
this.UpdateServerState();

[code2=csharp]public void UpdateServerState()
{
if (this.Connected == false)
{
return;
}

this.UpdateServerState(
GameApplication.Instance.WorkloadController.FeedbackLevel,
GameApplication.Instance.PeerCount,
GameApplication.Instance.WorkloadController.ServerState);
}[/code2]

Yes - thats correct.

Thanks for the detailed response.

Any idea when the failover feature would be available. In azure, reboots are fairly common. Hence the question.
