The folks at Microsoft Press have given everyone an early Xmas present with the release for download of a new e-book titled 'Introducing Microsoft System Center 2012 R2, Technical Overview'.
I've taken a quick scan through the content and it looks like they've covered everything that you need to know as an introduction to the System Center 2012 R2 suite of cloud and datacenter management products. An added bonus for me is that my good friend and ex-workmate John McCabe wrote a significant piece on the new Service Management Automation (SMA) tool working with the Windows Azure Pack in Chapter 10.
A big thanks has to go to the main authors Mitch Tulloch and Symon Perriman along with all of the other expert contributors to this book for making it a free resource to the general community - well done all!
