Where to Start: Service Oriented Architecture Is a Reality, But How Should You Take Advantage of It? (March 2006)
"Changing the cost equation permanently requires that CIOs reengineer their IT architectures to enable their systems to grow increasingly responsive and cost-effective over time. This has been the holy grail of IT in recent years, and in the beginning seemed just as elusive as the grail the knights looked for in the Middle Ages. Now, however, this seems to have finally changed. Many of the technologies and standards necessary to create such architectures are maturing and becoming widely adopted. After a relatively slow start, service oriented architecture (SOA) is beginning to live up to its promise."
