Abstract: Service Oriented Architecture based integration is a solution to the problem of the complexity of the integration of point-to-point, the integration hub-and-spoke as well as the integration of enterprise message bus. The aim of the research was to use service-oriented architecture (SOA) based integration method and technology through open-source that can integrate various information systems in a company or inter-companies without disturbing daily business operation. The outcome of this research can be used for integrating Information Technology and Communication (ITC) based infrastructure and services, especially for Small Medium Enterprise (SME) and various nonprofit institutions that cannot afford to buy the expensive licensed integration software. Aside from that, it can also be used as a basis in building industrial networking that connect SME, Industry and Government into Cloud Computing public infrastructure.
