I got sick and tired of throwing my money at unreliable, overpriced hosting solutions, only to discover I could do it at a fraction of the cost at home, and without ever opening a single port to the public.

It's fantastic, though I should add that my Proxmox and Unraid are separate hardware, as with my Raspberry-Pi DNS Servers and Proxmox backup machine.
After started with Unraid a little over a year ago, this motivated me to move to a real hypervisor Unraid can virtualize, dockerize, etc, but has far too many drawbacks to justify the hardware commitments, though it was an excellent starting point.
Add to this, a (custom) DNS and SSL termination, and we well on our way to a proper home lab setup.
It's worth mentioning that while there are people virtualizing Unraid on Proxmox, that the implications of inter-service dependencies were just not worth the hassles against diversifying backend services.
Next up; UPS, pfSense (router), and forwarding DNS servers on a 10GbE backplane :D

Proxmox, unraid, pihole ftw
