                                       Figure V.1 – Service provisioning in DaaS system


            As shown in Figure V.1, service provisioning is the design or modification of DaaS configuration to meet the
            various types of CSC. All types of CSC try to connect their virtual desktop environment with the client and the
            CSP provides the service in accordance with these types. Service provisioning consists of the following:
            •       Account provisioning: It makes and manages the CSC account with regard to CSC type.
            •       Server and resource provisioning: It supplies or manages hardware resources that are requested
                    from the CSC.
            •       Virtual desktop provisioning: It generates, supplies and manages the virtual desktop environment
                    to be allocated to the CSC.

            •       Software provisioning: It installs, manages or updates the software in the DaaS platform and virtual
                    desktop environment.
            •       Storage provisioning: It manages and backs up offline files of virtual machine, user data and other
                    storage-related files related to virtual desktop environment.
