Exam AWS Certified Developer Associate topic 1 question 225 discussion

Exam question from Amazon's AWS Certified Developer Associate
Question #: 225
Topic #: 1
[All AWS Certified Developer Associate Questions]

A developer is using an AWS CodeCommit repository to store source code for an application. The developer is using an AWS CodePipeline pipeline to deploy the application. The pipeline does not start automatically and must be started manually when a deployment is needed.

The developer needs to configure the pipeline to start automatically.

Which solution meets this requirement with the LEAST delay?

  • A. Create a webhook in the CodeCommit repository to directly call the CodePipeline API to start the pipeline.
  • B. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to start the pipeline upon the detection of changes in the CodeCommit repository.
  • C. Configure the pipeline to poll the CodeCommit repository for changes and to start automatically when changes are detected.
  • D. Create a CodeCommit trigger for an Amazon Simple Notification Service (Amazon SNS) topic. Configure the SNS topic to post to the CodePipeline API to start the pipeline.

In my opinion A or C because a codepipeline should be designed to be run as soon as a developer push the source control system. Even if it is possible, why we do have to configure it by using CloudWatch Event to detect changes in the repository?

LEAST DELAY - A (Webhook) Both AWS CodePipeline's webhook feature and AWS EventBridge can be used to trigger AWS CodePipeline when changes are made to the AWS CodeCommit repository. However, in terms of speed, AWS CodePipeline's webhook feature is faster since it is specifically designed to work with AWS CodePipeline and can trigger the pipeline immediately when changes are pushed to the CodeCommit repository. On the other hand, AWS EventBridge is a more general event-driven service and may have some additional overhead when routing events to the appropriate target, such as the AWS CodePipeline service. This can introduce some delay between the time changes are made to the CodeCommit repository and the time the pipeline is triggered. Overall, if the goal is to trigger the AWS CodePipeline with the least delay possible, using AWS CodePipeline's webhook feature is the recommended approach.

Selected Answer: B
When using CodeCommit, Amazon ECR, or Amazon S3 as the source for a pipeline, CodePipeline uses an Amazon CloudWatch Event to detect changes in the source and immediately kick off a pipeline. When using GitHub as the source for a pipeline, CodePipeline uses a webhook to detect changes in a remote branch and kick off the pipeline
