An introduction to service-oriented computing

This excerpt from "SOA: Principles of Service Design" introduces service-oriented computing's new generation of computing platforms and all the elements therein.

service-oriented computing Service-oriented computing represents a new generation distributed computing platform. As such, it encompasses many things, including its own design paradigm and design principles, design pattern catalogs, pattern languages, a distinct architectural model, and related concepts, technologies, and frameworks.

It sounds like a pretty big umbrella, and it is. Service-oriented computing builds upon past distributed computing platforms and adds new design layers, governance considerations, and a vast set of preferred implementation technologies. That's why taking the time to understand its underlying mechanics before proceeding to the actual design and construction phases of a delivery project is time well spent.

To better appreciate the fundamental complexion of a typical service-oriented computing platform we need to describe each of its primary parts, which we'll refer to as elements:

  • Service-Oriented Architecture
  • Service-Orientation
  • Service-Oriented Solution Logic
  • Services
  • Service Compositions
  • Service Inventory

The following sections define each of these elements and conclude with a section that explains how they can inter-relate conceptually and physically. The basic symbols introduced in these sections are used repeatedly within subsequent parts of this book.
