Abstract: Analyzing the conceptions and characteristics of the software services based on Software as a Service (SaaS) model concludes that the current Service-oriented Architecture (SOA) cannot be used to realize software services directly. In addition, with the view of expanding software service application and realizing diversity of software services, software services based on SaaS model should support service customization and multi-terminals. By extending the SOA, software service terminal, software service port and software service register model were introduced. An architecture of software services based on SaaS model which supports multi-terminals and service customization was presented. The structure and work flow of the architecture were also presented. The experimental results prove that the architecture can realize software service based on SaaS model, and also supports the requirements mentioned above.
