A homelab is a place where you can try out new things and learn new technologies
or new vendor equipment in the comfort of your own home. For me, I've got virtual firewalls to practice
with for a Cert that I'm trying to get.
It's all about creating a space to work in so you can
improve on your skill set with the tools you feel you need at your fingertips. We run our own servers,
Why? because it's fun, and you can dramatically improve the quality of life for yourself and those
who you live with, being able to unlock your front door with your face is cool, being able to
understand what's going on to make that happen (zoneminder watching the cameras, openCV looking
for known faces and firing a script off to tell openHAB to unlock the door), and why it might
not be such a great idea (easily defeated with a photo) is even cooler. It's a hobby, and one
that, compared to many others, has a lower barrier to entry and overall cost, with very large
rewards.
If you're looking to get into it down below are parts that i used in my Current homelab. i am still a beginner so further research is recommanded
