Following my post yesterday, I had a discussion today about how CEC fits within Windows architectures.
This is the home page for Windows Server System - click on Infrastructure environment to see a diagram of the solutions and architectures including CEC. You can also find business benefit, products and links to trial software from this site. Other elements that you should be aware of are Dynamic Systems Initiative (DSI) and Windows Server System Reference Architecture (WSSRA). WSSRA has many great documents within that are really helpful including design, management and best practise.
