Which AWS tool helps manage version control of code?

AWS CodeCommit is designed specifically for managing version control of code. It is a fully managed source control service that enables teams to host secure and scalable Git repositories. With CodeCommit, developers can easily collaborate on code by enabling them to push changes, create branches, and manage pull requests, which are essential features for version control.

Version control is crucial for software development as it tracks changes to the codebase, allowing multiple team members to work simultaneously without overwriting each other's changes. CodeCommit integrates seamlessly with other AWS tools and can be used as part of a continuous integration and continuous deployment (CI/CD) pipeline, but its primary focus is on providing a reliable platform for managing code versions securely.

In contrast, other options such as AWS CodePipeline, AWS CodeDeploy, and AWS CodeBuild serve different purposes in the development lifecycle. CodePipeline automates the workflow for building, testing, and deploying code; CodeDeploy manages the deployment of applications to various environments; while CodeBuild provides a service for compiling source code, running tests, and producing ready-to-deploy software packages.
