Abstract: One of the fundamental problems prevailing IT in the past is the weak link between business units and IT. Various efforts have been initiated to alleviate the problem, and the most prominent revolutionary remedy may be Enterprise Architecture (EA), and the Service Oriented Architecture (SOA). Driven by an organization’s business goals and strategy, EA discipline defines and maintains various architecture models under a unifying EA framework (such as Zachman, US federal government’s Federal Enterprise Architecture and IBM’s EA Framework), and governance and transition initiatives needed to effectively co-ordinate semi-autonomous business units towards a common business goal. SOA (and web services), on the other hand, extended the fundamental approach of EA by offering an enabling technology that is based on establishing a well-understood portfolio of reusable and composable business services that can be either statically linked or dynamically discovered and linked, and consumable by any other business services if they can comprehend and have sufficient rights to do so. In this way, enterprise business applications developed in such a service-oriented approach can enable the business to adapt to ever changing business environment in a much more flexible and rapid fashion.
This tutorial will lead the audiences the evolution from EA to SOA, explain some key underpinning concepts and architectural aspects and the resulting benefits of adopting SOA. More importantly we will explain how EA and SOA can help organizations to realize those potential benefits and achieve and sustain a continuously high ROI on such investments.
