Cloud adoption Test Lab Guides (TLGs) - Link
Use these cloud adoption Test Lab Guides (TLGs) to set up demonstration or dev/test environments for Office 365, the Enterprise Mobility Suite (EMS), Dynamics 365, and Office Server products.
TLGs help you quickly learn about Microsoft products. They’re great for situations where you need to evaluate a technology or configuration before you decide whether it’s right for you or before you roll it out to users. The "I built it out myself and it works" hands-on experience helps you understand the deployment requirements of a new product or solution so you can better plan for hosting it in production.
TLGs also create representative environments for development and testing of applications, also known as dev/test environments.
