Nowadays, non-integrated system is one of the most common problems in enterprise or organization. Most departments in the enterprise have information systems developed based on their non-standardized requirement processes which often propose different platforms, non-standardized business processes, and non-easy data transfer protocols. Unfortunately, the departments realize that they have big problem when they have to span business processes across enterprise and have to transfer and integrate data smoothly. As one possible solution, web service is proposed as a data exchange technology used to integrate data and business processes. In this paper, we describe the most common architecture of web service nodes used in integration processes. Then we analyze the weakness of this architecture, especially if it is used in integration of complex enterprises or organizations, and then propose new architecture called centralized-star architecture as a proposed solution. This new architecture was designed and implemented in Institute Technology of Bandung (ITB) under I-MHERE project.
