Once the request is received, the controller computes a prediction of a first sustainability impact based on the service characteristic for an implementation of the cloud service on a high quality of service (QoS) server operating in the cloud, and also computes a prediction of a second sustainability impact based on the service characteristic for an implementation of the cloud service on a high sustainability server operating in the cloud. The controller then presents the first and second predicted sustainability impacts to the cloud user so that the cloud user can make an informed decision with regard to the new cloud service request.
