DVA-C02 Deployment Practice Question
A development team wants to automatically deploy a web application to Amazon EC2 instances when new code is pushed to the master branch of an AWS CodeCommit repository. Which AWS service should the team use to orchestrate the build, test, and deployment phases?
⚠ Common exam trap
It's easy for candidates to confuse AWS CodeBuild with CodePipeline because both can be triggered by CodeCommit pushes, but CodeBuild alone cannot orchestrate multiple sequential phases like testing and deployment, which is the key requirement in the question.

Correct answer & explanation
✓
AWS CodePipeline
AWS CodePipeline is the correct service because it is a fully managed continuous delivery service that orchestrates the entire build, test, and deployment phases as a pipeline. It can be configured to automatically trigger on code pushes to the master branch of an AWS CodeCommit repository, then invoke AWS CodeBuild for building and testing, and finally deploy to EC2 instances via AWS CodeDeploy, providing end-to-end automation.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS CloudFormation
Why it's wrong here
AWS CloudFormation is primarily designed for provisioning and managing AWS infrastructure as code, allowing developers to define resources like EC2 instances, databases, and networking components in templates. While it can deploy infrastructure necessary for a web application, it does not inherently handle the compilation, testing, or continuous deployment of the application's code onto that infrastructure. Its role is infrastructure creation and updates, not application release orchestration.
- ✗
AWS CodeBuild
Why it's wrong here
AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs unit tests, and produces deployable artifacts. It serves as a vital component within a CI/CD pipeline, specifically executing the build and test phases. However, CodeBuild itself does not orchestrate the entire end-to-end process, which includes fetching source code from repositories, managing approval steps, or deploying the built application to target environments.
- ✓
AWS CodePipeline
Why this is correct
AWS CodePipeline is a fully managed continuous delivery service that automates release pipelines for rapid and reliable application and infrastructure updates. It orchestrates the entire CI/CD workflow, seamlessly integrating with various AWS services like CodeCommit for source, CodeBuild for build and test, and CodeDeploy for deployment. This comprehensive orchestration capability makes it the ideal choice for automatically deploying a web application through a defined, multi-stage pipeline.
- ✗
AWS CodeDeploy
Why it's wrong here
AWS CodeDeploy is a service that automates application deployments to a variety of compute services, including Amazon EC2, AWS Fargate, AWS Lambda, and on-premises servers. Its core function is to execute the deployment of application revisions to target environments. However, CodeDeploy does not manage the preceding stages of a complete CI/CD pipeline, such as retrieving source code, compiling it, or running automated tests; it solely focuses on the deployment action itself.
