Uncertain among the Deep Cloud Cover: Service Innovation Model and Evolution of Mobile Cloud Services
Mobile cloud service innovations are continuously generated; however, we still do not know the innovationmodel. This study adopts case study method and collected a total of 687 events of service innovation delivered by Chung-Hwa Telecom from 2004 to 2016. This study aims to build a service innovation model based on a five-dimension perspective of mobile cloud service and also taking both subjects served and degree of integration into considerations. Moreover, the five dimensions concern Infrastructure as a Service (IaaS), Software as a Service (SaaS), Platform as a Service (PaaS), Device as a Service (DaaS), and Content as a Service (CaaS). Finally, this study obtains the findings as follows. In the aspect of service development, IaaS is continuously developed but shows a slow trend. Moreover, due to deriving many innovative business models by mobile cloud service, SaaS shows a multiplier effect even if it shows a dramatically decreasing trend. The case moves towards generating PaaS and hence CaaS becomes a dramatically increasing trend. However, DaaS shows a dramatically decreasing trend. In the aspect of service provision, the proportion of high-integration services is far greater than that of low-integration services. The trend of provision of high-integration services is moving from “people” type to “things” type, which shows that the concept of Internet of Things (IoT) becomes a new service core of mobile cloud services. The study suggests PaaS and CaaS be the core of service development of IoT and communities of mobile network be deeply emphasized.
