Service-Oriented Architecture and Enterprise Architecture, Part 1: A Framework for Understanding How SOA and Enterprise Architecture Work Together

Overview

Close examination of SOA and EA and their corresponding governance reveal a great deal of overlap in their concepts, activities, processes, and outcomes. For example, both require input based on business objectives and produce outcomes that are tied to and measured against these objectives. Furthermore, both aim to address issues on the enterprise level (strategy and planning, reference architecture, and so on), and at the same time their governance models are similar. An enterprise that's adopting SOA while developing EA and its governances may encounter problems if the similarities and overlaps between EA and SOA are not recognized and accounted for.
