I've had several incarnations of the self-hosted home lab for decades. At one point, I had a small server farm of various machines that were either too old to serve as desktops or that people simply no longer wanted. I'd grab those machines, install Linux on them, and use them for various server purposes. Here are two questions you should ask yourself:
In the past decade, we've seen two major advances in software development: cloud-native architecture and artificial intelligence. The first redefined how we build, deploy, and manage applications, and the second is becoming a mainstream utility. Now, the two are converging, prompting developers to reevaluate both their skill sets and architectural strategies. This convergence isn't just future talk. It's today's competitive reality.
