Abstract: A tangible machine readable storage medium stores instructions and implements a method when the instructions are executed by a processor. A service catalog (SC) includes a service unit (SU). The SU includes an array of service resources (SR) to define a service using end-user service-oriented terminology. The SU is assigned to a module. The module includes a component associated with a configuration and a device. An operational task is executed on the device to deploy the configuration on the device to implement the service.
