Answer: AWS CloudFormation

## Explanation **AWS CloudFormation** is the correct answer because it is specifically designed for Infrastructure as Code (IaC). Here's why: - **AWS CloudFormation** allows you to model and provision AWS resources using templates written in JSON or YAML format - You can create, update, and delete entire AWS infrastructure stacks in a predictable and repeatable way - It manages dependencies between resources automatically - Provides version control for infrastructure configurations **Why the other options are incorrect:** - **AWS CodeBuild** is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages - **AWS Systems Manager** is a management service that helps you automatically collect software inventory, apply OS patches, create system images, and configure Windows and Linux operating systems - **AWS Trusted Advisor** is an online resource that helps you reduce cost, increase performance, and improve security by optimizing your AWS environment Infrastructure as Code (IaC) is a key DevOps practice that enables managing and provisioning infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools.
