Looks familiar? Sure, because the operating system currently running in an Azure Instance is Windows Server 2008. It is not strange to see so many old faces here. Nevertheless, there are some new services, such as "Cloud Drive", "OS Diagnostic Service" and "RdAgent", with corresponding processes namely clouddrivesvc.exe, osdiag.exe and rdagent.exe.

The functionality of "OS Diagnostic Service" is quite straight forward according to its name. But for other two services? Who knows?
