SOA, or Service Oriented Architecture, is a style of software design where services are provided to the other components by application components through a communication protocol over a network. SOA also describes a set of principals and guidelines for creating and using these services. The main goals of SOA are loose coupling, re-usability, independent evolvability, composability and the abstraction of underlying implementation details.
Oracle SOA transforms complex application integration into agile and reusable service-based connectivity by mediating, routing, and managing interactions between services and applications in the enterprise. SOA allows integration of widely disparate applications on multiple implementation platforms.
The Service Oriented Architecture paradigm has been around for many years, but recent advances in technology have led to a renewed interest in SOA and its ability to create scalable, extensible and adaptable software architectures. While SOA still has its detractors, there is no doubt that it has proven itself as a powerful tool for creating complex applications. As the world of enterprise software continues to evolve, it is likely that SOA will play an increasingly important role. As such, it is essential for architects and developers to remain abreast of the latest SOA developments.
