The RTM of Windows Server 2012 marks the initiation of a frenzy of Microsoft releases in the upcoming months, and Satya Nadella, Microsoft’s head of Server and Tools Business, points to the its launch as a statement in the company’s mission to create the so-called "Cloud OS". With the release of the (somewhat impressive) SkyDrive, the company has made no secret of its desire to seamlessly integrate cloud services into its software, and will certainly need to deliver on those promises in order to appease consumers.
Windows 8 RTM was released to MSDN and TechNet subscribers last month.
