The Engineer now wants automated email notifications whenever OpsWorks restarts an instance when the instance is deemed unhealthy or unable to communicate with the service endpoint. How can the Engineer meet this requirement?

ACreate a Chef recipe to place a cron to run a custom script within the Amazon EC2 instances that sends an email to the team by using Amazon SES if the OpsWorks agent detects an instance failure.

BCreate an Amazon SNS topic and create a subscription for this topic that contains the destination email address. Create an Amazon CloudWatch rule: specify as a source and specify auto-healing in the initiated_by details. Use the SNS topic as a target. aws.opsworks

CCreate an Amazon SNS topic and create a subscription for this topic that contains the destination email address. Create an Amazon CloudWatch rule specify as a source and specify instance-replacement in the initiated_by details. Use the SNS topic as a target. aws.opsworks

How should the deploy stage be configured to meet these requirements?

AUse AWS CloudFormation to publish a new version on every stack update. Then set up a CodePipeline approval action for a Developer to test and approve the new version. Finally, use a CodePipeline invoke action to update an AWS Lambda function to use the production alias

BUse CodeBuild to use the AWS CLI to update the AWS Lambda function code, then publish a new version of the function and update the production alias to point to the new version of the function.

CUse AWS CloudFormation to define the serverless application and AWS CodeDeploy to deploy the AWS Lambda functions using DeploymentPreference: . Canary10Percent15Minutes
