+====== Infrastructure as Code (IaC) ======
-This section covers topics related to automation in DevOps, focusing on Scripting and Infrastructure as Code.
+Infrastructure as Code (IaC) is a practice that allows you to manage and provision infrastructure through code, rather than manual configurations. The central idea is that infrastructure can be treated like software: versioned, reusable, and automated. IaC aims to improve consistency, scalability, and agility by enabling the creation and management of resources programmatically.
-==== Scripting ====
+=== Benefits of IaC ===
-- {{devops:automation:scripting}}
+  * **Consistency**: Minimizes human errors and ensures that configurations are the same across all environments.
-  Documentation and examples for automating tasks using scripts.
+  * **Scalability**: Makes it easier to create infrastructure quickly and automatically.
+  * **Automation**: Allows IaC to be integrated into CI/CD pipelines for automated deployment.
+  * **Reusability**: Scripts and configurations can be reused across multiple environments and projects.
+  * **Auditability**: Enables detailed version control of the entire infrastructure.
-  ===== devops:automation:scripting:overview =====

+=== Best Practices ===
-    How Ansible is used in automation and its role in configuration management.
+  * **Version Control**: Use Git to version infrastructure code.
+  * **Modularization**: Break down the code into reusable modules.
+  * **Testing**: Validate IaC scripts and templates in a test environment before deploying to production.
+  * **Automated Deployment**: Integrate IaC with CI/CD pipelines for automated infrastructure deployment.
