Using architectural patterns and blueprints for service-oriented architecture

Using software patterns and blueprints to express a service-oriented architecture's fundamental principles supports the efficient use of SOA technologies for application development. Understanding SOA and all of its implications for software applications requires introducing a set of architectural principles that define SOA more concretely. Software patterns and blueprints can accommodate both forward and reverse engineering. Using the core SOA principles, software architects can derive best-practice pattern systems and catalogs that illustrate how to leverage existing SOA technologies.

1. Driving Forces

The central objective of a service-oriented approach is to reduce dependencies between “software islands,” which basically comprise services and the clients accessing those services. These service-oriented software systems need to balance the following forces:
