This shift, known as Infrastructure as Code (IaC), allows infrastructure to be defined, provisioned, and managed using machine-readable definition files, applying software development practices like version control, testing, and automated deployment.</p> <p>At the heart of creating dynamic, reusable, and maintainable Terraform configurations are three fundamental concepts: variables (input variables), outputs, and local values. These elements enable you to write flexible code that can adapt to different environments and requirements without constant modification, making your infrastructure truly &ldquo;as code&rdquo;. This tutorial will guide you through mastering these essential Terraform components. <div class="toc"> <nav id="TableOfContents"> <ul> <li> <ul> <li><a href="#1-terraform-variables-the-inputs-to-your-infrastructure">1.
