Proactivity breeds predictability and the chance for better business opportunities

摘要

Service oriented architecture (SOA) is the latest in a long line of ideas that have sought to define a flexible and efficient way that technology-based services can be joined together to achieve business goals. A service based on an SOA is designed to perform a structured set of tasks and return the results of those tasks. It offers a great deal of value - especially in the areas of web services standards, flexibility and the relative simplicity of representing applications and processes to business analysts. But SOAs have their limitations. Unpredictable events happen all the time, and SOAs on their own struggle to cope with them. In a service oriented architecture, how do users know that a relevant, unpredicted event has occurred in real-time? How can they change the process to respond appropriately to that event straight away? SOA does not allow for this.
