About this Book
The key to succeeding with service-oriented architecture (SOA) is in comprehending the meaning and significance of its most fundamental building block: the service. It is through an understanding of service design that truly “service-oriented” solution logic can be created in support of achieving the strategic goals associated with SOA and service-oriented computing.
Formally endorsed by senior members of Intel, Microsoft, Oracle, IBM, BEA, Sun, Intel, HP, and SAP, this acclaimed book provides a thorough exploration of service engineering as it guides you through a comprehensive, insightful, and visually rich exploration of the service-orientation design paradigm, revealing exactly how services should and should not be designed for real-world SOA.
This book’s coverage includes:
- Over 240 full-color illustrations
- A concise introduction to SOA and service-oriented computing concepts and benefits
- A thorough exploration of the service-orientation design paradigm as represented by eight specific design principles
- A comparison of service-oriented and object-oriented concepts and principles and a clear definition of what qualifies as “service-oriented” logic
- Detailed coverage of four different forms of service-related design granularity
- An exhaustive examination of service contracts, with an emphasis on standardization, abstraction, and the utilization of WS-Policy, XML Schema, and WSDL definitions
- A comprehensive study of various forms of service-related coupling with an emphasis on the requirements to attaining a suitable level of loose coupling.
- An inside look into how commercial design approaches are incorporated to achieve truly agnostic and reusable service logic
- Techniques for maximizing service reliability, scalability, and performance by instilling high levels of autonomy and emphasizing stateless design
- Approaches for positioning services as highly discoverable and interpretable enterprise resources
- Unprecedented coverage of how to design services for participation in complex compositions
- The definition of concrete links between each design principle and the strategic goals and benefits of SOA and service-oriented computing
- Numerous cross-references to key design patterns documented separately in SOA: Design Patterns
The goal of this book is to help you attain a solid understanding of what constitutes contemporary SOA along with step-by-step guidance for realizing its successful implementation.
