Azure cloud service - is VIP exchange activated to enable OnStop ()?

I have an Azure cloud service with a network and a working role. When Azure Cloud Services is suspended, the OnStop () method is called.

In a VIP exchange, does it call the same OnStop () method when deploying the outbound service as soon as the VIP exchange is requested? http://msdn.microsoft.com/en-us/library/microsoft.windowsazure.serviceruntime.roleentrypoint.onstop.aspx

Also, what is the order of events during the VIP exchange? Presumably, the working OnStart () method of the new deployment starts at some point, but is it up to the OnStop () of the outbound deployment? I'm trying to figure out if two work roles (inbound and outbound deployment) will be performed simultaneously, or if there will be a slight gap in the character role service.

As far as I know, when you make changes to the VIP exchange, it happens at the router / firewall level, and not at the cloud service level. Your cloud service continues to run, and the OnStop () event does not fire. As mentioned in the documentation here: http://msdn.microsoft.com/en-us/library/windowsazure/hh386336.aspx

When a service advances to production, VIPs and URLs that were assigned to the production environment are assigned to a deployment that is currently in an intermediate environment, thereby “promoting” production services. The VIP and URL assigned to the environment are assigned to the deployment that was in the production environment.
