Technical Concepts of Service Orientation

Abstract

This chapter presents service-oriented concepts from a technological perspective. Before delving into service orientation, concepts in component orientation are introduced for a point of reference. After, service orientation is introduced via the service-oriented interaction pattern and the entities that participate in it, followed by a discussion of how these entities and service orientation, in general, relate to component orientation. The technical presentation is followed by a survey of several service-oriented platform technologies, including: CORBA Traders, JavaBeans Context, Jini, OSGi, and Web services. The purpose of this chapter is to present service-oriented concepts from a technological perspective, position them with respect to those present in component orientation, and illustrate how they are realized.
