Which service stores and manages Git repositories in the cloud with private by default repositories?

• A. AWS CodeArtifact
• B. AWS CodeCommit
• C. AWS X-Ray
• D. AWS Cloud9

Answer: (B)

Hosting Git repositories in the cloud with private by default is what this service is built to do. AWS CodeCommit is a fully managed Git repository hosting service that stores and manages Git repositories in the cloud, with repositories private by default. It provides IAM-based access control, encryption at rest and in transit, high availability, and seamless Git workflow support (clone, commit, push, pull). It integrates with CodePipeline and other AWS services for CI/CD, making it easy to automate releases without managing infrastructure. The private-by-default setup means your code isn’t exposed publicly unless you explicitly grant access, which aligns with common security practices for source control. Other options don’t fit this role: CodeArtifact is a package manager for binaries and libraries, X-Ray is a tracing service for distributed applications, and Cloud9 is a cloud-based IDE (which can use Git but does not host Git repositories itself).
