The Recipe for Modern IT
In the traditional world of IT, setting up a server was a craft. A sysadmin would log in, click through menus, install packages, and tweak settings until everything worked. I know, I did this job for much of my early career. But much like a chef cooking a complex signature dish from memory, this manual approach has a fatal flaw: human variability. If the chef forgets one pinch of salt or a single sprig of thyme, the dish changes. In IT, we call this Configuration Drift. Infrastructure as Code (IaC) solves this by turning that “memory” into a precise, digital recipe. Instead of manually configuring hardware or virtual machines, you write machine-readable files that define exactly what your environment should look like.
