Name change alert! You might be familiar with MSDN Subscriptions and it’s useful to know that they’re now called Visual Studio Standard Subscriptions. Note that this is distinct from a monthly or annual subscription to Visual Studio Professional/Enterprise which is called a Cloud Subscription.
There are two useful documents which might help you at this transition time: “Understanding Visual Studio Standard Subscriptions” and “Managing Visual Studio Standard Subscriptions”.
You can find them with the rest of the Microsoft licensing guides here: http://bit.ly/MSLicensingGuides.
