SOA en-us Copyright 2006-2008, SOA Systems Inc. http://www.soamag.com/I17/0408-1.asp Distributed application development has proliferated business data throughout the enterprise, resulting in a web of dependent and redundant data silos that adversely affect enterprise agility. Many assumed that by merely adopting SOA these complexities would be magically abstracted and a method for seamlessly aggregating this data for consumption would manifest itself. However, it turns out that for most larger IT enterprises challenges, such as variations in data quality, differing primary keys, and multiple systems of record, have created a situation where real-time aggregation of data is impractical. Master Data Management (MDM) has emerged as a potential solution for removing this barrier. SOA http://www.soamag.com/contributors/bio-cmadrid.asp#When:15.04.08 http://www.soamag.com/I10/0907-2.asp The concept of virtualization is being widely embraced throughout enterprises and their collective data centers. The benefits are undeniable: resources are more highly utilized, flexibility gains result in quicker times to market; and an opportunity emerges for increased visibility by leveraging hooks in the abstraction layer. By applying virtualization to services, organizations can start to realize the potential that SOA has offered but has been challenged to deliver. This article will discuss a proven approach to service virtualization and will demonstrate it via a case study wherein a company faces common real world challenges as they adopt Web services and service-orientation.
