What is SOA?
June 6th, 2010 | admin
Web services promote an environment for systems that is loosely coupled and interoperable. Many of the concepts for Web services come from a conceptual architecture called service-oriented architecture (SOA). SOA configures entities (services, registries, contracts, and proxies) to maximize loose coupling and reuse. This chapter describes these entities and their configuration in an abstract way. Although you will probably use Web services to implement your service-oriented architecture, this chapter explains SOA without much mention of a particular implementation technology. This is done so that in subsequent chapters, you can see the areas in which Web services achieve some aspects of a true SOA and other areas in which Web services fall short.
Before we analyze the details of SOA, it is important to first explore the concept of software architecture, which consists of the software’s coarse-grained structures. Software architecture describes the system’s components and the way they interact at a high level.
