With System Center 2012 the different products of the family became components. This was not just changing of words. This change has the goal to tip that all components come in one license and that their integration is way better compared to the previous versions. To help us leverage that integration community project created Integration guides for System Center 2012 components:
The purpose of the Integration Guide is to provide an overview of each System Center component in its role as a programmable platform to be leveraged for the Microsoft Private Cloud. It is intended to provide an abstraction layer that guides partners and customers on their decision process for methods to build automated solutions across System Center components and between System Center and other systems.
