Why running each service on its own mini PC can boost security and lower energy use
If you’ve been tinkering with servers and containerization, you’ve probably noticed one catch: your main servers can get pretty power-hungry when running multiple containers. I recently stumbled on a different containerization approach that’s been a bit of an eye-opener. Instead of cramming multiple containers into a single server, why not run each service on its own micro PC? It sounds a bit old school, but the results are surprisingly decent.
Why rethink your containerization approach?
The idea with containerization is to efficiently use your hardware by running isolated services within one server. But in practice, having all those containers running on your main servers can increase power consumption more than you’d expect. In my case, I found that one micro PC running a service uses less power than adding another container to a big server. By offloading each service to a tiny, dedicated machine, the overall power consumption dropped by about 15%. That’s nothing to sneeze at, especially if you’re thinking green or trying to cut costs.
Better separation means better security
One of the biggest benefits I’ve seen with this approach is improved security through physical separation. Virtual separation helps, but if one container is compromised, there’s still some risk it might affect others on the same host. When each service runs on its own machine, that risk falls away. Your network attack surface gets sliced up physically. It’s a simple yet effective way to isolate critical apps.
You might wonder if clustering all those micro PCs would be complicated. Sure, it’s a bit more setup work compared to a single server running multiple containers. But for small setups or services where security and power efficiency matter, the tradeoff feels worth it. Plus, micro PCs these days are pretty affordable and surprisingly capable.
Getting started with distributed containers on micro PCs
If you want to try this approach, start with your most critical or power-hungry containers. Pick a micro PC for each that fits the performance requirements (devices like Intel NUCs or Raspberry Pi 4s can do the job depending on your needs). Then isolate your services by assigning each to a dedicated micro PC. You might even find that administration becomes simpler since each device only runs one service.
This isn’t the typical containerization story you hear, but that’s kind of the point. Sometimes, going back to basics with a twist can uncover unexpected benefits like energy savings and security improvements.

Trying this different containerization approach might not fit everyone’s needs, but if you’re curious about balancing power consumption with built-in security, it’s worth a shot. And hey, sometimes the simplest setups can surprise you with their efficiency and control.
