Welcome to the first post in what I’m calling my “Planetary Datacenter” series. Essentially, I’ve got a homelab that I’ve been tinkering with for a while, building, refining, and sometimes breaking it (on purpose!) to learn how to make it better. Now, I’m ready to share everything I’ve learned so far.

I jokingly refer to my setup as a “Planetary Datacenter” because it stretches beyond just my house. Thanks to clever networking and tools like ZeroTier, I can place services just about anywhere on the globe (hence “planetary”) and still have them communicate as if they were right next to each other on my local LAN. If you’re into homelabs, networking, or just curious about how to structure your own multi-machine environment, stick around.

I first introduced this idea at a CNCF Galicia talk, where I discussed how I use ZeroTier and WireGuard to interconnect various machines. Over time, I realized that combining ZeroTier with my local hardware gave me a pretty powerful setup: everything in one “big” virtual LAN, accessible anywhere.
