Toward Customer-centric SOA: Services Resource Active Provisioning Approach

With the rapid development of services computing, services expression, registration and assembly have been partially solved. But for the ultimate goal of computing, namely on-demand service, it has not been able to achieve by far, especially active provisioning approach for services resource. Faced with key issue for requirements-dominated services virtualization, active services resource provisioning will be focused. Customercentric SOA (Service-oriented Architecture) will be systematically investigated with requirements model and distributed requirements elicitation. In this paper, we have established software architecture with personalized active customization for services resource that will select unsatisfactory requirements fragment of customers to dynamically generate custom needs during services composition. By means of custom preferred provider selection designated to push the customization requirements, service providers complete the services resource production and customized products evaluation just in time, and the process will effectively prevent failure of services aggregation and services resource provisioning exceptions occurring. These efforts of the work will improve ondemand services resource provisioning capability. The experimental results and prototype show the efficiency and effectiveness of our approach.
