Active and Adaptive Services Resource Provisioning with Personalized Customization

Software as a service(SaaS), we are moving to the age of service-oriented software engineering(SOSE). But for the goal of services computing, namely on-demand service, it has not been able to achieved by far, especially the active provisioning approach for services resource. In view of these facts of services aggregation, i.e. The relative deficient services resource, single provision structure and passive selection mode for service requesters. Active provisioning of services resource with personalized customization will be focused. In this paper, we have established software architecture with personalized active custom for services resource. Customization of the active provisioning of services resource mainly includes two aspects: Firstly, for unmatched services resource of service composition, sliced or segmentation method should be chosen to acquire the individual needs of services resource according to the overall requirements. Secondly, a huge amount of legacy software will be comprehensively reused, namely servicelization. Through personalized customization of services resource, it will achieve on-demand active provisioning to furnish adequate material for dynamic services aggregation. It will also provide the production framework, process guidance and engineering support of CASE tools for services resource provisioning in runtime based on personalized customization. The feasibility and efficiency of the proposed approach are verified by a series of experiments.
