I think there is a similarity and differences between EA and SOA and they are overlapped with each other. for example, 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 governance may encounter problems if the similarities and overlaps between EA and SOA are not recognized and accounted for. If we look at business architecture domain, SOA address the business processes while EA addresses the business architecture. >From application architecture domain, SOA address servcies and components while the EA address the application architecture as a whole. Integration middle ware architecture domain, SOA addresses Integration architecture / ESB, while EA concerns with technology architecture. Data archiytcure is addressed by SOA while EA address the information architecture. and from operations architecture domanis, SAO addressesQoS, security, monitoring & infrastructure while EA again concerns with the whole technology architecture. As Dr. Mamdouh Ibrahim, from IBM advices us, "To reduce headaches in the process, make sure you have well-planned architecture governance and SOA governance models as well as a better understanding of how they should work together. And take advantage of the lessons learned by those who have gone before you—like the ones we've outlined in this article—to save time and money during your own engagement."
