Which AWS service assists in setting up Continuous Integration/Continuous Deployment (CI/CD) pipelines?

AWS CodePipeline is specifically designed to facilitate the creation and management of CI/CD pipelines. It automates the workflow of deploying code changes through various stages, from the source repository to building, testing, and ultimately deploying the application. This is achieved by integrating with other AWS services, such as CodeCommit for version control, CodeBuild for building applications, and CodeDeploy for deployment.

By using CodePipeline, developers can define their application's release process as a series of stages and actions, streamlining the deployment process. This leads to more efficient software development cycles, enabling teams to deliver updates to their applications quickly and more reliably. The service provides a visual representation of the pipeline, helping teams to monitor progress and troubleshoot any issues that arise during the deployment process.

In contrast, although AWS CodeDeploy is crucial for automating the deployment of applications, it does not manage the entire pipeline. AWS CloudFormation is a service for defining and provisioning cloud resources through code but does not handle the CI/CD process itself. Amazon EKS is a managed Kubernetes service for deploying containerized applications, which also does not directly provide a CI/CD solution.
