Designing Service-Oriented Architectures

Abstract

A service-oriented architecture (SOA) is a distributed software architecture that consists of multiple autonomous services. The services are distributed such that they can execute on different nodes with different service providers. With a SOA, the goal is to develop software applications that are composed of distributed services, such that individual services can execute on different platforms and be implemented in different languages. Standard protocols are provided to allow services to communicate with each other and to exchange information. In order to allow applications to discover and communicate with services, each service has a service description, The service description defines the name of the service, the location of the service, and its data exchange requirements (Erl 2006, 2009).
