Service-Oriented Architecture Best PracticesA proven roadmap for delivering on the promise of service-oriented architectureEnterprise SOA presents a complete roadmap for using service-oriented architectures to reduce cost and risk, improve efficiency and agility, and liberate yourself from the vagaries of changing technology.While other books focus on low-level technical details, this book identifies pragmatic architectural strategies and project management techniques for the entire SOA lifecycle: planning, design, implementation, testing, rollout, and maintenance. The authors introduce crucial measures for supporting service-oriented architectures outside the IT organization. Then, to illuminate the realities of SOA deployment, they present four end-to-end case studies drawing on their experiences in a wide range of industries. Along the way, you'll discover how to: * Calculate and communicate the economic value proposition for SOA * Link SOA to business process management * Use SOA to overcome the formidable challenges of distributed system design and development * Make your business technology independent, by focusing on architecture, not specific interfaces * Go beyond individual projects to establish an effective long-term SOA roadmap * Manage infrastructure heterogeneity when eliminating it isn't realistic * Recognize the nontechnical success factors for SOA in the enterprise * Reflect lessons from Credit Suisse, Halifax Bank of Scotland, and other world-class enterprisesWhether you're a manager, architect, analyst, or developer, ifyou must drive greater value from IT services, Enterprise SOA will show you how-from start to finish.
