<ul><li>Terraform modules are essential for scalable infrastructure as code, enabling encapsulation and reuse of configurations.</li><li>A Terraform module contains related resource definitions in cohesive configuration files.</li><li>Modules promote scalability, maintainability, and collaboration within DevOps workflows.</li><li>These modules mirror software engineering principles, treating configurations as composable building blocks.</li><li>Root modules and child modules serve distinct purposes in organizing and executing Terraform configurations.</li><li>Root modules act as the entry point, defining global settings and integrating child modules.</li><li>Child modules are reusable templates for specific resource sets, promoting consistency and reuse.</li><li>Terraform module sources include local directories, Terraform Registry, GitHub, Bitbucket, and other platforms.</li><li>Modules enhance usability, maintainability, and interoperability by logically grouping resources and exposing configurable inputs.</li><li>The Terraform Registry hosts a variety of modules for AWS, Azure, and other providers, simplifying infrastructure management.</li></ul>
