The Evolution of Infrastructure

For years, system administrators managed cloud resources by clicking through the AWS or Azure web consoles. This is known as ClickOps. It is slow, prone to human error, and impossible to replicate exactly.

What is Infrastructure as Code (IaC)?

IaC is the practice of managing and provisioning computing infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools.

Why it matters:

1. Speed: Deploying an entire data center in minutes.
2. Consistency: The code always produces the same result.
3. Version Control: You can track changes in Git.

In this course, we focus on the CLI (Command Line Interface). Everything we do will happen in the terminal.
