WSUS Design
When designing your Windows Update Server Services (WSUS) infrastructure, there are a number of options available to you. I have developed a Windows Update infrastructure scenario diagram to help make the decision a little easier. Ideally you would want to use option 3 (bottom-left) but I have deployed a network that used option 1 (top-left). This doesn't provide all the possible options, but does list the main possibilities.
