Connecting Raspberry Pi, Proxmox, and VPS into One Developer Playground

Over time, my projects spread across three machines: a Raspberry Pi, a Proxmox lab, and an Oracle Cloud VPS. Managing them separately became tedious, so I decided to interconnect them into one seamless playground.

I used Cloudflare Tunnels to bridge all three environments securely, allowing me to access services across systems as if they were part of one private network. Proxmox hosted my heavy workloads, the Pi handled always-on lightweight services, and the VPS acted as my external gateway.

This hybrid setup taught me how distributed infrastructures actually operate. When one node went down, the others could still serve requests — small-scale redundancy that mirrored enterprise cloud design.

Takeaway:
Linking multiple systems into a unified environment showed me that distributed design isn’t about size — it’s about connection. Whether it’s a Pi or a VPS, every node can have a purpose in your developer ecosystem.
