1                                    Framework and requirements for cloud computing


            Two sub-roles of cloud service partner are involved in this case, cloud service developer and cloud auditor.
            The cloud service developer develops the implementation of the cloud services using the development tools
            functional component and tests the service using the test management functional component. The cloud
            service  is  then  packaged  with  deployment  information  and  given  to  the  CSP:cloud  service  manager  to
            perform the deploy and provision services activity resulting in a service capabilities functional component
            being offered in the provide services activity. The cloud auditor, in the meantime, performs the perform
            audit and report audit results activities on the cloud service developer, cloud service provider or cloud
            service customer according to the policies and governance regimens of each.

            After the CSP:cloud service manager performs the deploy and provision services activity, the provide services
            activity uses the service capabilities functional component, which is the implementation of the service and
            which  in  turn  uses  the  resource  layer  functional  components  for  the  compute,  storage  and  network
            resources required to run the service. The provide services  activity also involves integrating the service
            capabilities functional component with the security systems functional component to provide security and
            protection  of  personally  identifiable  information  capabilities  such  as  data  encryption.  The  operational
            support systems functional component supports management, monitoring, automation and configuration
            for the services and resources. In addition, the CSP:cloud service manager performs the perform service level
            management  activity.  The  perform  service  level  management  activity  manages  the  availability  and
            performance of the cloud service so that it meets the objectives defined in the SLA which applies to the cloud
            service.  The  service  level  management  functional  component,  the  monitoring  and  reporting  functional
            component, and the incident and problem management functional component are used to accomplish this.
            Sometimes, CSP:cloud service managers provide the service in collaboration with another CSP:cloud service
            manager, invoking cloud services in that peer cloud service provider. The CSP:cloud service manager then
            performs the manage peer cloud services activity to set up the contracts and SLAs for using the peer cloud
            service. The peer cloud service provider also offers administrative and use cloud computing activities: the
            provide services and the perform service level management cloud computing activities, just like any other
            cloud service provider.
            These  are  a  common  set  of  cloud  computing  activities  for  a  CSP:cloud  service  manager,  but  there  are
            additional cloud computing activities that could be performed and are documented in this specification.
            Once a cloud service is available for use, two cloud service customer sub-roles perform various activities.
            First, the CSC:cloud service administrator performs the administer tenancies activity using the administrator
            function functional component, to set up the tenancy and to grant access rights to CSC:cloud service users.
            Once this is done, CSC:cloud service users perform the use cloud service activity by leveraging the user
            function  functional  component  to  interact  with  the  cloud  service.  Meanwhile,  the  CSC:cloud  service
            administrator typically monitors the service to ensure that it is running correctly and meeting the terms of
            the SLA, again using the administrator function functional component.
