Infrastructure as Code

Stop clicking buttons and typing commands by hand. Describe your infrastructure as text, version it, and let a tool make reality match it.

Prerequisite: Cloud Fundamentals

What you'll actually learn

Clicking through a cloud console to build a server works fine until you need to build the same thing twice, or explain exactly what's running and why. This track treats infrastructure as text you write, review, and version like any other code — Terraform-style declarations, state that tracks what actually exists versus what you asked for, and the specific discipline of planning a change before you apply it so you know what's about to happen before it happens.

What you'll be able to do

You'll write a config that provisions real infrastructure, deliberately let it drift from reality, and use a plan step to catch and reconcile the difference before anything breaks — the exact skill that separates "I ran some Terraform once" from being trusted to touch infrastructure other people depend on.
