Next Generation SOA

Más información sobre el libro

SOA is now a mainstream computing discipline, with accelerating adoption among organizations of all types and sizes. Increased ROI, enhanced organizational agility, and reduced IT burdens are all driving justifications for the significant investments needed to undertake these initiatives. Yet, despite the growing number of SOA implementations, field-proven best practices and use cases are only now emerging. In "Next Generation SOA," Thomas Erl helps you use them to maximize the business value of "your" SOA investments. Erl, a top-selling IT author and SOA expert, has written the ideal SOA introduction for "today's" IT professionals. This practical, use-case-driven guide distills the real-world practice of building successful service-oriented software systems. Accessible and jargon-free, it answers crucial questions IT professionals ask about SOA today -- and the questions they "need" to ask about crucial issues such as integration, security, and governance. Coverage includes: What exactly is loose coupling, and why does it matter? What is an ESB, and why do I need one? What are the worst SOA design errors, why do people keep making them, and how can I avoid them? How do I implement SOA to address projects of all sizes? How do I categorize services and define their requirements? What crucial lessons have been learned about securing services in SOA environments?
