SOA Patterns
Service orientation involves distributed systems collaborating, sharing information, and integrating seamlessly. This unique nature of Service-Oriented Architecture (SOA) presents new challenges for architects and system designers.
Just as the object-oriented paradigm has well-defined design patterns to address recurring problems, the SOA world has also made efforts to identify and document solutions in the form of SOA design patterns.
Recently, Prentice Hall announced the publication of SOA Design Patterns by Thomas Erl, which introduces 85 design patterns for SOA. Alongside the book's release, the new SOAPatterns.org community site was launched. This platform serves as a forum for further development and refinement of SOA design patterns.
Contributors
Key contributors to the book and SOA pattern development include:
- David Chappell and Clemens Utschig from Oracle

- Dennis Wisnosky, Chief Architect and Chief Technical Officer at the U.S. Department of Defense

SOA Design Patterns Poster
I have contributed to the "SOA Design Patterns Poster" on SOAPatterns.org. This poster visually catalogs the 85 design patterns from SOA Design Patterns (Thomas Erl, Prentice Hall, Copyright 2008).
The poster provides a concise reference for SOA architects, designers, and developers, offering a single-page (A2 size) or two-page (A3 size) view of all patterns, categorized with brief descriptions.
Posters in both A2 and A3 sizes are available for download at:
