             Title            Self-service use case
             Description      CSP provides cloud services to the market. For improvement of CSC experiences, the CSP
                              provides self-service method to CSCs (e.g., web portal or other automated approaches) to
                              discover, purchase, configure, deploy, activate and deactivate cloud service and to check cloud
                              service status.

            I.3     Service maintenance use case

             Title            Service maintenance use case

             Description      A CSP provides cloud services to the market. For the stability and availability of its service,
                              periodic maintenance is needed. For a good customer experience, the maintenance cannot
                              result in a long suspension and deactivation of a service. Therefore it is required that CSP can
                              provide automated software enabled cloud services to shorten the maintenance time.
             Roles            CSP
             Figure (optional)   /
             Pre-conditions   –  The CSP can provide automated software enabled cloud services.
             (optional)
             Post-conditions   –  The duration of suspension and deactivation is reduced markedly.
