Which solution is the MOST operationally efficient way for the developer to receive approval from the product owner?
Add a new stage to CodePipeline before the production deployment. Add a manual approval action to the new stage. Add a new notification rule in the pipeline settings. Specify manual approval as the event that initiates the notification. Specify the SNS topic’s Amazon Resource Name (ARN) to notify the product owner.
Develop an AWS Step Functions state machine that sends a notification to the product owner and accepts an approval. Add a new stage to CodePipeline before the production deployment. Add the state machine as a Step Functions action to the new stage.
Add a manual approval action to the existing production deployment stage in CodePipeline. Specify the SNS topic’s Amazon Resource Name (ARN) while configuring the new manual approval action.
Edit the settings in CodePipeline. Create a new notification rule. Specify manual approval as the event that initiates the notification. Create a new notification target. Specify the SNS topic to notify the product owner. Save the notification rule.
Explanations:
This option adds a new stage to CodePipeline specifically for manual approval, which is a built-in feature. It allows the product owner to approve or reject the deployment. Using an SNS topic for notifications ensures that the product owner is immediately informed when action is needed. This approach is operationally efficient and leverages existing AWS capabilities effectively.
While using AWS Step Functions is a valid approach, it introduces unnecessary complexity for this scenario. The developer would need to create and manage a state machine, which adds overhead. Additionally, integrating Step Functions into CodePipeline requires more configuration compared to the built-in manual approval action, making it less operationally efficient.
Adding a manual approval action to the existing production deployment stage is incorrect because CodePipeline requires the approval step to be in a separate stage for it to pause the pipeline until approval is granted. This option also does not explicitly use SNS notifications, which could lead to a lack of proper communication with the product owner.
This option focuses solely on creating a notification rule without incorporating a manual approval action in the pipeline. While notifications are important, without a structured approval process in CodePipeline, the deployment cannot be effectively controlled. Therefore, it does not provide an efficient means for the developer to obtain the necessary approval.
