What Is Infrastructure as Code? A Beginner-Friendly Practical Guide
What Is Infrastructure as Code? A Beginner-Friendly Practical Guide Imagine setting up a cloud server manually. You log in to a cloud platform, select a server size, configure storage, set network rules, and adjust security settings. Now imagine repeating the same process for development, testing, and production environments. Doing this manually takes time, and small differences between environments can cause problems. This is where Infrastructure as Code (IaC) becomes useful. It allows teams to define and manage infrastructure through configuration files instead of depending entirely on manual setup. Tools such as Terraform help DevOps engineers automate infrastructure provisioning, make configurations reusable, and manage changes in a more consistent way. In this guide, let's understand what Infrastructure as Code means, why it matters, how Terraform works, and how beginners can get started.
