A company wants to rapidly set up a continuous integration and continuous delivery (CI/CD) pipeline. Which AWS service should they choose?

AWS CodeStar is the correct choice because it provides a unified interface for developing, building, and deploying applications on AWS. It quickly sets up an entire CI/CD toolchain, including source control, build, test, and deployment services, with pre-configured project templates. This allows for rapid pipeline creation. AWS Config is incorrect because it is a service for assessing, auditing, and evaluating the configurations of your AWS resources, not for CI/CD. Amazon Cognito is incorrect as it provides authentication, authorization, and user management for web and mobile apps. AWS DataSync is incorrect because it is a data transfer service that simplifies, automates, and accelerates moving data between on-premises storage and AWS storage services.
