The book I read to research this post was Implementing An Advanced Server Infrastructure by Steve Suehring which is a very good book that I bought on kindle. This book is aimed at those taking the MCSE exam and if you are just looking for a general introduction to Windows Server 2012. The book only covers the subject in a general way and expects you to have a working knowledge although there are lots of links to websites and blogs to need to read about it in more detail. This book mostly covers setting up users and hows Windows Server automates this. You can set up a range of users called a scope using these kinds of features. In Windows users have roles which are general permissions on the computer different to what we call permissions which are object based normally with in a program. The two biggest updates with in Windows Server 2012 are probably cloud computing and virtualization. Cloud computing is websites generally that offer web based software or software as a service. This is normally something you don’t download although there are exceptions which are then called hybrid computing. Virtualization which can often be run with out an operating subject to having the computer meet certain requirements which is called on the metal is normally a client with in a client especially for going on the internet with limited permissions. This limits damage that can be done by malware because certain things are simply disabled. Something you also need is certificates of called CA’s or certificate authorities and you should always use a 3rd party provider. This encrypts information going from one computer to another so have to be installed at both ends. You normally install certificates into AD FS or active directory federation services. I did enjoy reading this book and do recommend it. It is around 450 pages so is a substantial length to.
