For those wanting to build a base configuration of Windows Server 2012 R2 in a Windows Azure hosted lab environment, Microsoft has now released a step-by-step guide. The guide allows for a quick setup of the configuration so there's less time required to actually install it.
This new guide teaches how to build the lab in a Windows Azure Virtual Network.
Test Lab Guides are the resulting documentation after Microsoft performs significant work implementing their own technologies and then recording and sharing the experience. The docs not only allow you to implement the same technologies in your own testing environment, but they also give you a unique understanding of potential gotchas and the breadth of work required to bring the technologies to life within your infrastructure.
