Product Description
The authors of this definitive book on SOA debunk the myths and demonstrate through examples from different vertical industries how a crawl, walk, run approach to deployment of SOA in an IT environment can lead to a successful return on investment.
One popular argument states that SOA is not a technology, but that it stands alone and can be implemented using a wide range of technologies. The authors believe that this definition, while attractive and elegant, doesnt necessarily pass pragmatic muster.
This book describes both the technical and organizational impacts of adopting SOA and the pursuant challenges. The authors demonstrate through real life deployments why and how different industry sectors are adopting SOA, the challenges they face, the advantages they have realized, and how they have (or have not) addressed the issues emerging from their adoption of SOA. This book strikes a careful balance between describing SOA as an enabler of business processes and presenting SOA as a blueprint for the design of software systems in general. Throughout the book, the authors attempt to cater to both technical and organizational viewpoints, and show how both are very different in terms of why SOA is useful. The IT software architect sees SOA as a business process enabler and the CTO sees SOA as a technology trend with powerful paradigms for software development and software integration.

SOA can be characterized in terms of different vertical markets. The vertical markets covered include healthcare, government, manufacturing, finance, and telecommunications. SOA considerations are quite different across these vertical markets, and in some cases, the required organizational shifts and technology shifts are highly divergent and context dependent.
Whether you are a CTO, CIO, IT manager, or IT architect, this book provides you with the means to analyze the readiness of your internal IT organization and with technologies to adopt a service oriented approach to IT

Service Oriented Architecture Demystified: A pragmatic approach to SOA for the IT executive
