IaC with Terraform

Infrastructure as Code (IaC) is less about “writing config files” and more about adopting an operating model: version control, reviewable changes, repeatable environments, and a safer way to evolve infrastructure over time.

Terraform is popular for IaC because it lets you describe infrastructure declaratively and then converge real environments to match that desired state. That unlocks consistency across teams and environments, reduces manual error, and makes changes auditable and reversible.

In the full guide, we cover:

• What IaC means in practice and why Terraform fits the model
• The Terraform workflow (author → validate → plan → apply) and how teams collaborate around it
• Core concepts you’ll want early: state, providers, modules, and environment separation
• Common pitfalls (drift, secrets, and unsafe changes) and how to avoid them
