Microsoft System Center is one of the three pillars of Microsoft’s Cloud OS vision that will transform the traditional datacenter environment, help businesses unlock insights in data stored anywhere, enable the development of a wide range of modern business applications, and empower IT to support users who work anywhere while being able to manage any device in a secure and consistent way. The other two pillars of the Cloud OS are, of course, Windows Server 2012 R2 and Windows Azure, and Microsoft Press has recently released free Introducing books on these platforms as well.
