🌐 What is Terraform?

Terraform is an open-source Infrastructure as Code (IaC) tool developed by HashiCorp. It allows you to define your cloud infrastructure using simple configuration files written in HCL (HashiCorp Configuration Language).

Instead of manually clicking through the AWS console, Terraform lets you define everything in code—making your setup more efficient, reusable, and easier to manage.

✨ Real-World Example

Let’s say you want to create an EC2 instance on AWS. Instead of logging in to the console every time, you can define it once in a .tf file and reuse or update it whenever needed—with a simple apply.

This not only saves time but also reduces the chances of human error.
