            –       Check  and  control  service  status:  It  supports  CSCs  to  control  cloud  services,  such  as  stopping,
                    resuming  and  terminating  the  cloud  services.  Also,  this  activity  involves  checking  the  status  of
                    running cloud services by monitoring so that the cloud service broker enforces service qualities
                    agreed in a SLA instead of CSCs.


            6.3     Service model of cloud service brokerage
            The cloud services registered in the product catalogue of cloud service brokerage are categorized in the
            following three service models:
            –       Cloud service aggregation: As shown in Figure 6-2, cloud service aggregation brings together cloud
                    services  from  multiple  CSPs  to  CSCs  without  any  changes  in  a  product  catalogue.  The  detailed
                    description of cloud service aggregation is introduced in Table I.2 of Appendix I;
            –       Cloud service integration: As shown in Figure 6-3, cloud service integration collects registered cloud
                    service  in  a  product  catalogue,  making  them work together to  provide  new  cloud  services  in  a
                    product catalogue. The detailed description of cloud service integration is introduced in Table I.3 of
                    Appendix I;

            –       Cloud  service  customization:  As  shown  in  Figure  6-4,  cloud  service  customization  performs
                    customized development by a cloud service broker on existing multiple cloud services in a product
                    catalogue according to CSCs' demands. The detailed description of cloud service customization is
                    introduced in Table I.4 of Appendix I.
