Dynamic Interoperability Between Multi-Tenant SaaS Applications

Enterprise Interoperability has been becoming an important area of research to ensure the competitiveness and growth of enterprises. While Software as a Service (SaaS), the new service delivery model offers a set of advantages for enterprises in sharing software with lower cost, the loosely coupled and multi-tenant features of SaaS model bring new chanllenges of interoperability between two SaaS applications. This paper proposes a platform to delivery SaaS application for enterprises. Among the multi-tenant SaaS applications, service based interoperability is introduced by extending the SCA specification with interoperability interfaces. Then a method of service interoperability supported by ESB and a dynamic service routing mechanism is discussed in details. At last, an experiment is introduced to evaluate the dynamic routing mechanism and show the effectiveness.
