There are plenty of lab platforms available today. Yes, Hyper-V isn't the trendiest choice anymore. There are more advanced solutions with richer orchestration and automation capabilities.
I still use Hyper-V.
Not because it's the best platform, but because it does exactly what I need, and over the years I've automated almost everything around it.
Instead of manually creating virtual machines every time I need to test something, I built a collection of PowerShell templates for Windows 10, Windows 11, and several Linux distributions. Creating a new lab no longer means spending half an hour clicking through installation wizards.
- Need a clean workstation? A couple of clicks.
- Need a domain controller, a certificate authority, a file server and a print server? Same thing.
Within minutes I can rebuild a standard Active Directory environment and start testing.
The real benefit isn't saving a few minutes of installation time. It's making experimentation almost frictionless.
When a customer reports a strange Group Policy behavior, I can reproduce their configuration in a clean environment and validate a theory before suggesting a change. If I need to verify a deployment sequence, test a PowerShell script, or understand how a Windows feature behaves, I don't have to wonder whether my own environment has been affected by previous tests.
I simply build another one.
Most of the automation relies on PowerShell. Virtual machines are created automatically, operating systems are deployed from prepared images, and post-installation configuration is handled through scripts. Server roles such as Active Directory, Certificate Services, File Services or Print Services can then be installed and configured automatically.
Building something like this isn't particularly complicated, but it does require a good understanding of Windows deployment, imaging, unattended installations, PowerShell, and the services you're trying to automate.
The investment pays for itself surprisingly quickly.
Instead of saying "I think this should work," I can usually say "I tested it." That makes customer discussions much easier and significantly reduces the risk of making recommendations based on assumptions.
It's one of those internal projects that nobody outside my office will ever see, but it probably saves me more time than many of the tools I've published publicly.
There is one downside, though.
When it's 35°C outside and the lab has been running all day, I eventually leave my office and discover that my apartment has quietly turned into a small datacenter, withou the efficient air conditionning !
