• wherein the requirement of the cloud service client is used as a criteria for searching the cloud service;
• and
• perform a management function of the cloud service,
• wherein the cloud service broker delivers a control request for the cloud service from the cloud service client to a cloud computing system among the multiple cloud-computing systems,
• wherein the cloud service broker initiates validation of a control status of the cloud service after the cloud service broker receives an acknowledgement from the cloud computing system, and
• wherein the cloud service broker provides a checking period by predicting completion time of the validation of the control status.
