Service Based Approaches for Enterprise Architecture Planning


One of the recent issues in Enterprise Architecture planning is how to design service based architectures. This paper attempts to review several efforts related to this concern. Based on literature and our evidences, these approaches can be located in three categories: integration of SOA and EA, expansion of EA layers and Service-Oriented EA. First category incorporates SOA concepts into EA planning. Second category extends existing EA layers with new Service Layer and last category attempts to design and develop all EA layers using services. Based on our investigations, a service based framework has been developed by the authors for using an extension of EA including service architecture layer for implementation of ITIL V3.
