Architecture for using Azure Worker Role

We are investigating Photon on premise server, and intend to deploy to Microsoft Azure Cloud Service worker role. Some questions are not cleared:

1. How to start the server? Is there any API we can call inside OnStart method of WorkerRole.cs? Or we have to use the PhotonControl.exe to start the service which is not applied to our architecture, we hope everything is done by the code, not manually.
   
2. About Load Balancing, if I understand correctly, we can simply make use Azure Cloud Service load balancer, without your provided Load Balancing SDK, any risk we may meet?
   

Our game is just like this: two players joined one room, and doing some fight. The two players are selected by some logic(skills etc.), what we want to achieve is we can scale out our instances count once customer became huge number, so Load Balancer is something we have to consider before the development.

Thanks.
