Hosting the SharePoint 2013 three-tier test lab on a Windows Server 2012 Hyper-V server
Microsoft test lab guides are deliberately written to be independent of how you actually put them together. For example, you can use physical components (computers and switches/hubs), virtual components (virtual machines and virtual networks/switches), or a combination. For virtual components, you can use the virtualization technology of your choice.
For SharePoint Server 2013, the new Hosting the SharePoint Server 2013 three-tier test lab with Windows Server 2012 Hyper-V article includes diagrams, guidance, and step-by-step procedures that take you through building out the SharePoint Server 2013 three-tier farm test lab environment on a single Windows Server 2012 Hyper-V server.
This article tells you how to turn the conceptual three-tier farm test lab, which looks like this:
