Hey guys. I spent the last 6 months writing some software for Windows, and it might be such a big hit that I need to put it in the cloud. What kinds of changes will I need to make to my Windows software to port it to a cloud server?

For example, right now, I don't have to keep track of a USER ID -- but if we move the software to the cloud, I will need to somehow capture a USER ID. How does the user log in?

Is there a Windows command to get the USER ID? Is that the same command I will use in the Cloud environment?
