Service-oriented architecture (SOA) is the IT industry’s latest attempt to promote the concept of component reusability in the development, integration, deployment and maintenance of enterprise applications. SOA promises to deliver the speed and adaptability companies need by making their applications more service driven. A Yankee Group survey of 473 enterprise decision-makers reveals that 75 percent of them plan to invest in SOA technology in 2005. Gartner predicts that by 2009, SOA will play a dominant role in new application projects.”]
