Managing cloud infrastructure by hand gets messy fast. Infrastructure as Code (IaC) comes to the rescue - letting you define, provision, and version your infrastructure the same way you manage application code. In this article I introduce the core IaC concepts and show how tools like Terraform make cloud provisioning repeatable and automated.
It’s a beginner-friendly starting point if you keep hearing “IaC” and want to understand what the fuss is about. It pairs with my open-source Terraform IaC Starter repository if you’d like to try it hands-on.
