Abstract: Since resource service is provided for requirement in SaaS system, platform is overloaded by processing mass data. It extends standard MVVM pattern, and increases processing module on Web, and deploys Service-Oriented Computing environment in the module. In this paper, SOC model is designed to be used for logical processing of quality assessment of resource service. This model makes users utilize Cloud Computing service by means of Web and contributes to Cloud Computing platform. Preliminary experiments reveal that, by using this model, processing pressure of SaaS platform providing resource service is reduced effectively. At one time, service quality is improved and systemic extendibility is enhanced.
