By the end of this phase

You can explain IaC, how Terraform compares to alternatives, and the plan/apply workflow, and you have Terraform installed.

What Is Infrastructure as Code?

Instead of clicking through a cloud console, you describe servers, networks and databases in files, review them like code, and recreate them any time. Learn declarative vs imperative and why IaC makes infrastructure repeatable and auditable.

How Terraform Works — Providers, State & the Core Workflow

Terraform reads your configuration, compares it with the real world (stored in state), shows a plan of changes, and applies it through providers that talk to cloud APIs. Learn the write → init → plan → apply → destroy loop.

Terraform vs OpenTofu, Pulumi, Ansible & CloudFormation

Know the landscape. OpenTofu is the open-source fork of Terraform under the Linux Foundation; Pulumi uses general-purpose languages; CloudFormation is AWS-only; Ansible focuses on configuring servers. Most Terraform skills transfer to OpenTofu.

Install Terraform & Your First Config

Install the CLI and an editor with HCL support, then create your first resource. Docker works for a no-cost start: you can learn without any cloud account.
