What Is Terraform?

Terraform is an open-source Infrastructure as Code (IaC) tool developed by HashiCorp. It allows you to define, provision, and manage cloud infrastructure using human-readable configuration files written in HCL (HashiCorp Configuration Language). Instead of manually clicking through cloud dashboards, you write declarative code that describes your desired infrastructure—and Terraform makes it happen.

Why Use Terraform?

  • Cloud-Agnostic: Works with AWS, Azure, GCP, and many others.
  • Declarative Syntax: You describe what you want, not how to do it.
  • Version Control: Infrastructure changes can be tracked like code.
  • Reusable Modules: Build once, use everywhere.
  • Immutable Infrastructure: Changes are applied safely and predictably
