A. Run the AWS-UpdateCloudFormationStack AWS Systems ManagerAutomation runbook when Systems Manager detects an UPDATE_COMPLETE event for the instance status of the CloudFormation stack. Configure the runbook to invoke the Lambda function.
B. Create a custom AWS Config rule that produces a compliance change event if the CloudFormation stack has an UPDATE_COMPLETE instance status. Configure AWS Config to directly invoke the Lambda function to automatically remediate the change event.
C. Create an Amazon EventBridge rule that matches the UPDATE_COMPLETE event pattern for the instance status of the CloudFormation stack. Configure the rule to invoke the Lambda function.
D. Adjust the configuration of the CloudFormation stack to send notifications for only an UPDATE_COMPLETE instance status event to the SNS topic. Subscribe the Lambda function to the SNS topic.
