Service-Cloud Model of Composed Web Services

Abstract

Dynamic composing Web services provides an efficient mechanism to offer complex large systems. Substantial progress has already been made towards composing Web services. Unfortunately, these approaches cannot build a model of the whole life cycle of composed Web services. In order to solve this problem, we designed a model named Service-Cloud model based on the forming picture of clouds in nature. Service-Cloud model can describe the whole life cycle of the composed Web services: discovery, compose, publish, and terminate. Based on Service-Cloud model, we also designed and implemented a prototype
