Service-oriented architecture (SOA) is not something that has come out of nowhere. It is a stable, evolved IT system that efficiently recycles software implementations for better business values. SOA works beyond packaged software to work for dynamic and versatile businesses. It is all about growth.
SOA is not simply an approach to distributed computing. It enhances the approach towards dynamic businesses, ahead of packaged software. It provides an amalgamation of services that can communicate with each other, whether it involves transfer of data or using a combination of services for a desired outcome.
Unlike a distorted picture that provides no insight, SOA provides an architecture or programming such that it allows you to call forth the entire image. It makes way for different processes of the business cycle to be available at one point in time. Therefore, SOA works across integrated platforms to pave a multiple-access path for all processes.
