AWS Technical Essentials Practice

The primary advantage of using AWS CodeBuild is that it automates the process of compiling and testing source code. This service enables developers to focus on writing code rather than managing the infrastructure necessary for building applications. With CodeBuild, source code is pulled from a variety of repositories, built through a continuous integration process, and then tested to ensure that the code meets the required standards. This automation speeds up the software development lifecycle by providing fast feedback on code changes, simplifying the testing and building of applications, and promoting a more efficient development workflow.

The other options focus on different aspects of software development but do not accurately represent the core functionality of AWS CodeBuild. CodeBuild is not designed for hardware procurement, comparing coding styles, or eliminating code redundancy. Its purpose is specifically centered around the automated integration and delivery of code, which is essential for modern DevOps practices.
