A company uses AWS CloudFormation templates to manage infrastructure for a public-facing application in its development, pre-production, and production environments. The company needs to scale for increasing customer demand. A developer must upgrade the Amazon RDS DB instance type to a larger instance.
The developer deploys an update to the CloudFormation stack with the instance size change in the pre-production environment. The developer notices that the stack is in an UPDATE_ROLLBACK_FAILED slate in CloudFormation.
