Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
CodeCommit: Source control service for storing and managing code
In a DevOps pipeline, AWS CodeCommit provides source control, CodeBuild compiles and tests code, CodeDeploy automates deployments, and CodePipeline orchestrates the entire CI/CD process. Common confusions include mixing up the roles of CodeCommit and CodeDeploy or CodeCommit and CodeBuild.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
CodeCommit: Source control service for storing and managing code
Why this is correct
AWS CodeCommit is a fully managed source control service that hosts secure, Git-based repositories, providing version control, branching, and pull request workflows. It stores and manages your source code and artifacts in private repositories with IAM-based access control, encryption, and integration with other AWS services. Unlike build or deployment tools, its scope ends at source management—no compilation or runtime deployment happens here.
CodeBuild: Build service for compiling source code and running tests
Why this is correct
CodeBuild is a fully managed continuous integration build service that compiles source code, runs unit tests, and produces deployable artifacts such as JAR files or container images. It spins up ephemeral build environments on demand, scales automatically, and can be invoked directly or orchestrated by CodePipeline. It is not involved in hosting repositories or pushing deployments to instances.
CodeDeploy: Deployment service for automating code deployments
Why this is correct
CodeDeploy is a fully managed deployment service that automates the rollout of application code and built artifacts to compute services such as Amazon EC2, AWS Lambda, and on-premises instances. It controls the pace of deployment using strategies like rolling, blue/green, and canary updates, and uses an AppSpec file to define lifecycle events like BeforeInstall and AfterInstall. It does not compile code or manage source control.
CodePipeline: CI/CD service for automating build, test, and deploy phases
Why this is correct
CodePipeline is a fully managed continuous integration and continuous delivery (CI/CD) orchestration service that automates the build, test, and deploy phases as a configurable release process. It models workflows as pipelines containing stages (for example, Source, Build, Test, Production) and integrates natively with CodeCommit, CodeBuild, CodeDeploy, and third-party tools like GitHub or Jenkins. Its primary function is orchestrating the entire release process rather than performing any single step itself.
CodeCommit: Service for deploying code to EC2 instances
Why it's wrong here
This is incorrect because CodeCommit is a source control service that stores and versions your code in Git repositories; it has no mechanism to deploy code to EC2 instances. Deployment—including pushing code to EC2, registering it with a load balancer, and managing the deployment lifecycle—is the responsibility of AWS CodeDeploy. Confusing the two would break the CI/CD pipeline because you would be expecting a Git repository to execute runtime operations that require deployment agents and orchestration.
CodeBuild: Service for managing source code repositories
Why it's wrong here
This is incorrect because CodeBuild takes source code from a repository and compiles, tests, and packages it; it does not host repositories or manage branches, commits, or pull requests. Managing source code repositories is the job of CodeCommit, which provides Git-based storage, access control, and collaboration features. CodeBuild only consumes code as input during a build—it never acts as the system of record for your source.
