What tool would you use to view and troubleshoot CodePipeline execution history?

1. AWS CloudWatch

2. AWS CodeDeploy

3. AWS CodeBuild

4. AWS CodePipeline itself

The correct answer is: AWS CodePipeline itself

To view and troubleshoot the execution history of AWS CodePipeline, using AWS CodePipeline itself is the most effective choice. CodePipeline provides an integrated view of the entire pipeline's workflow, allowing you to see each stage's status and the history of actions within those stages, including successes, failures, and any error messages that may have occurred during execution. By accessing CodePipeline directly, you can easily navigate through the different stages of the pipeline, examine the logs for individual actions, and understand how the code is moved through the various points of deployment and build. This makes it much easier to identify where issues may have arisen and allows for more efficient troubleshooting. Other tools like AWS CloudWatch can certainly play a role in monitoring and logging in conjunction with CodePipeline, but they do not provide the same level of detailed execution history for the pipeline itself. AWS CodeDeploy and AWS CodeBuild serve specific roles in deployment and build processes, respectively, but they lack the comprehensive view and management features for the overall pipeline execution that are available through CodePipeline.
