AWS DevOps Engineer Professional Practice Test

AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready to deploy. It is designed to automate the build and testing part of the software development process, which is a crucial component of continuous integration and continuous delivery (CI/CD). By managing the build environment, scaling automatically, and eliminating the need for dedicated build servers, CodeBuild allows developers to focus on writing code rather than managing infrastructure.

In contrast, AWS CloudFormation is primarily used for infrastructure as code, enabling the automation of resource provisioning and management rather than focusing on testing and building software. AWS Lambda executes code in response to events but does not inherently provide CI/CD capabilities. Lastly, AWS Elastic Beanstalk is a platform as a service (PaaS) that makes deploying applications easier but does not handle automated builds and tests in the same manner as CodeBuild. Therefore, the functionality and purpose of AWS CodeBuild distinctly positions it as the managed CI/CD solution among the options presented.
