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?

A comprehensive tutorial and reference for creating Web service contracts for service-oriented solutions.

The bulk of the book covers design principles, with material on service contracts, service coupling, service abstraction, reusability, and service autonomy. Final chapters offer a comparison of service-orientation and object orientation, and look at supporting practices

This book describes cloud computing as a service that is "highly scalable" and operates in "a resilient environment". The authors emphasize architectural layers and models - but also business and security factors.

The first start-to-finish, step-by-step guide to modeling and designing SOA. Using Service-Oriented Architecture (SOA), enterprises can deliver high-value business services more rapidly and effectively, and gain unprecedented flexibility and value from existing IT infrastructure. SOA has earned the support of virtually every major software provider, and some 75% of enterprises surveyed are now investing in SOA technology and expertise. In Service-Oriented Architecture: Concepts, Technology, and Design, the author of 2004's best-selling SOA book presents the first end-to-end-tutorial for modeling and designing successful service-oriented architectures from the ground up. Writing in plain English, Thomas Erl provides step-by-step process descriptions for analyzing and designing any service or service-oriented business process definition.

A formal catalog that provides a pattern language for building service-oriented solutions through solving common design problems, this text offers expert guidance in the form of proven design patterns (and anti-patterns) to minimize the risk and maximize the potential of service delivery in support of SOA.

A Field Guide to Digital Transformation is a complete tutorial on digital transformation concepts, tools, technologies and practices, organized into a proven industry framework for adoption.
