Deployment perspective of service pattern: Solve dynamic services with heterogeneous carrier description

In the context of the development of the modern service industry, emerging technologies such as the Internet of Things (IoT) and 5G have promoted the integration of a large number of service devices, increasing the complexity of the service ecosystem and accelerating its evolution process. Although the service model has summarized the business relationship in the service ecosystem from the four aspects of workflow, data flow, resource flow and value flow, it has not formed a systematic description of the heterogeneous devices where the service is deployed. Therefore, future service ecosystem modeling methods need to solve the following two problems: how to describe heterogeneous devices to provide guidance for the deployment of services, and how to enable the service ecosystem to adapt to the dynamic adjustment of services.In this paper, in order to solve the problem of dynamic addition and deletion of services and dynamic replacement of deployment carriers, we propose a service deployment description method(SDDM) based on holon concept, and integrate it with service pattern, then extend service pattern description language , namely carrier SPDL (SPDL-C). To validate our framework, we empirically conducted a case study in which we selected an intelligent warehouse management service pattern as the object of study to reveal how our approach could address future challenges. Finally, we summarize and discuss the innovation and significance of the work.
