Enterprise Architecture Planning for Enterprise University Information System Using the TOGAF Architecture Development Method

Abstract One of the important strategies in dealing with the development of information technology is the usage and increase of information systems support for the enterprise. Enterprise University Information System (EUIS), a product released by the University of Indonesia Computer Science Center, is a cloud-based system that can help the academic community-run main and supporting processes with data that can be tracked in real-time. EUIS is currently used by several clients. In the future, the company is targeting technological developments in EUIS that can be used by many other universities, so it can be easily adjusted and integrated with existing information systems at the client. Therefore, an update of enterprise architecture is needed to support the alignment of IT with existing business needs. The enterprise architecture design method used in Enterprise Architecture Planning (EAP) with the Open Group Architecture Framework (TOGAF). In this research using a qualitative methodology, TOGAF ADM can assist in planning architectural changes from monolithic to micro services by identifying several scenarios. The results showed that the decentralized microservice architecture design can be applied to EUIS. Pusilkom UI currently has implemented this design with a client that has condition 2, so that further research can be tested for other conditions.
