How to setup 2 instances?

Hi,

I'm wanting to create a Azure VM, install SQL Server, a custom application and RemoteApp. Then clients will login via RemoteApp to use the app. This is all OK.

However according to the SLA on Azure I need to have 2 instances of the Azure VM running to achieve the up time. How do I setup the Azure VM to have those 2 instances?

Can someone point me in the right direction?

Thanks, Jon
