To follow along on what we have been covered in this book, we strongly believe in learning by doing, and therefore we highly encourage you to try out all of the technologies and principles we covered in this book. You don't need a huge server. For most topics, you could use a single machine with Windows Server 2016 installed and 16GB of memory, and by enabling Hyper-V-nested virtualization, you could enable a few virtual machines to run concurrently. Ideally, though, having at least two physical servers will help with the replication and high-availability concepts. With Windows 10, Hyper-V client is included in the box. So even without any kind of real server, it is possible to explore many of the Hyper-V technologies.
