Jurnal Penelitian | JURNAL TEKNIK INFORMATIKA PLANNING AND DESIGN SOA ARCHITECTURE BLUEPRINT | Service-oriented architecture (SOA) is an architectural styles that modularized information system into services. With SOA, these important programs become business services. With one single business service for a given function that get used everywhere in organization. When business policy need to be changed, it can be changed in one place and because the same service is used everywhere, the consistency will be keep throughout the organization. SOA enables businesses to make business decisions supported by technology instead of making business decisions determined by or constrained by technology. With SOA, business gets to focus more on business and less on technology; this is the reason why business managers are going to like SOA.
Service-oriented architecture is all about building standard interfaces to access different business functions that are exposed by various core business backend systems. These functions could essentially be those that are frequently invoked by other business systems within the enterprise ecosystem. SOA enables business managers and IT to talk in business term that both sides understand. Without SOA, the IT developers and business manager typically use very different words to describe the process of creating programs.
Businesses keep changing and requests for new programs keep coming. What is new and different about business is the idea that businesses do not have to keep reinventing wheel. The idea behind a service oriented architecture is that the idea that can organize programs for easy reuse, for easy maintenance and support, for coherent, consistent results across organization, and for easily sharing data and resources. Service oriented architecture is to create flexible structure that will turn key IT software asset into reusable services that can be use no matter how the business changes
