Infrastructure as Code

From cloud platforms like AWS to automation tools like Terraform and Ansible, this section covers everything you need to provision, configure, and manage infrastructure the DevOps way.

As we previously explored in the #, setting up infrastructure used to be a marathon of manual tasks—ordering servers, mounting them in racks, cabling like a bomb squad, and configuring everything by hand. It was slow, error-prone, and about as fun as watching paint dry during a compliance audit.

Fast forward to today: infrastructure isn’t something you build with screwdrivers and sticky notes anymore. It’s something you define in code. Entire environments—servers, networks, storage—can now be created, configured, and destroyed with a few lines of script. No more guessing, no more “works on my machine,” and definitely no more waiting weeks for hardware deliveries.

This evolution is what makes Infrastructure as Code (IaC) the backbone of modern DevOps. It’s about automation, consistency, and speed. It’s how you scale without drama and recover from disasters without breaking into a cold sweat.

Cloud Infrastructure

Why the cloud changed everything and how services like AWS became the new data center.

Terraform

The tool that lets you build infrastructure like Lego—except losing a piece means production might go down.

Ansible

Because provisioning is only half the battle. Ansible makes sure your servers behave once they’re alive.

By the end of this chapter, you’ll understand why IaC is the foundation of modern DevOps and how these tools work together to make infrastructure predictable, scalable, and—dare we say—almost fun.
