http://www.soamag.com The SOA Magazine is a monthly online publication provided by SOA Systems Inc. and Prentice Hall/PearsonPTR and is officially associated with the "Prentice Hall Service-Oriented Computing Series from Thomas Erl." SOA en-us Copyright 2006-2007, SOA Systems Inc. http://www.soamag.com/I11/1007-3.asp The concept of software pipelines was developed as a methodology to enable service-oriented business solutions to implement concurrency while maintaining order of execution priorities and simplicity of application development. In order to effectively apply this methodology, it is helpful to have a solid understanding of its underlying principles. This article focuses on software pipelines law and rules and discusses the challenges and opportunities when they are applied to services-based business applications.

SOA http://www.soamag.com/contributors/bio-cisaacson.asp#When:05.10.07 http://www.soamag.com/I8/0607-3.asp Performance of service-oriented business applications is a constant concern and one that has led architects and developers to investigate a variety of architectural design options. This, the second in a series of articles, explores one such option in detail by showing how the software pipelines technology and methodology can be leveraged in real world scenarios. Two case study examples are provided, each utilizing software pipelines in a different business context. (First published in The SOA Magazine Issue VIII, June 2007.) SOA http://www.soamag.com/contributors/bio-cisaacson.asp#When:27.05.07 http://www.soamag.com/I5/0307-1.asp Many organizations have adopted SOA development models to deliver flexible and agile application components, but frequently ended up having to trade off performance and scalability in order to achieve these benefits. As service-oriented applications continue to grow in size and complexity, performance has become a foremost concern. Various optimization techniques exist to address runtime service performance concerns. This article explores these established design options and contrasts them with software pipelines, a new technology developed to accommodate service usage demands without compromising the flexibility and agility that is so important to achieving strategic SOA goals.
