Introduction to Infrastructure as Code · Lesson
What Is Infrastructure as Code?
Objective
Explain what Infrastructure as Code replaces, and why the config file itself becomes the documentation.
From clicking through a console to a text file
For decades, standing up a server meant clicking through a console, one screen at a time, and hoping you (or whoever's on call next) remembers exactly which buttons you pressed. Infrastructure as Code replaces that with a text file that describes the infrastructure you want - version-controlled, reviewable, and reproducible exactly, the same way application code already is.
Documentation that can't go stale
The file is the documentation, and it's never out of date, because it's the thing that actually built what's running.
