Until recently, many of the software technologies used for developing SOA-based solutions were limited to expensive, commercial offerings. However, that has now changed, and a compelling open source SOA platform can be implemented exclusively with open source products. Open Source SOA identifies a suite of open source products that can be used for a building SOA environment, and describes how they can be integrated by practitioners. It includes a hands-on introduction to the products selected; a multitude of source code examples; and implementation through real-life case studies.
