Infrastructure as Code

Learn how Infrastructure as Code lets you define cloud resources declaratively for repeatable, version-controlled, automated provisioning.

From Clicking to Code

Manually clicking through a cloud console to create servers and networks is slow, error-prone, and impossible to reproduce. Infrastructure as Code (IaC) defines your infrastructure in files you can version, review, and re-run.

Why IaC Matters

IaC brings software engineering discipline to infrastructure:

  • Version control and code review for changes
  • Reproducible environments (dev, staging, prod identical)
  • Automated, fast provisioning and teardown
  • Self-documenting infrastructure
