That said, please experiment. I have a homelab that I have some backups of, but I will tend to blow up and rebuild on a 3-month basis. Change the hypervisor this time, convert some web servers from NGINX to IIS, etc. Things like that. It again, keeps me up to date on the core technologies, and not the specific tooling, since it forces me into a different mindset. I don't think about "ok, how do I make my website accessible from the internal network in Windows", I think "Oh, I need a PTR record. How do I add that?"
