Clicking through a cloud console works for a first experiment, but it doesn't scale: nobody can review the changes, and rebuilding an environment means remembering every step. Infrastructure as code (IaC) solves this by describing servers, networks, and permissions in files that can be versioned, reviewed, and run again at any time.
You'll start with the idea itself and why teams adopt it, then move to two of the most widely used tools. Terraform is a provider-neutral tool that works across clouds, while AWS CloudFormation is Amazon's own template-based service for building and managing stacks of AWS resources.
The module closes with GitOps, an approach that treats a Git repository as the source of truth for what should be running and uses a tool such as ArgoCD to keep the live environment in sync with it. Next up is CI/CD and DevOps automation, where these definitions get tested and deployed automatically.
A simple explanation of how infrastructure as code lets you manage servers, networks, and cloud resources with code instead of manual setup, and why teams rely on it.
