Process-Driven SOA: Patterns for Aligning Business and IT supplies detailed guidance on how to design and build software architectures that follow the principles of business-IT alignment. It illustrates the design process using proven patterns that address complex business/technical scenarios, where integrated concepts of service-oriented architecture (SOA), Business Process Management (BPM), and Event-Driven Architecture (EDA) are required.

The book demonstrates that SOA is not limited to technical issues but instead, is a holistic challenge where aspects of SOA, EDA, and BPM must be addressed together. An ideal guide for SOA solution architects, designers, developers, managers, and students about to enter the field, the book:

- Provides an accessible introduction to basic and more advanced concepts in process-driven SOA

- Illustrates how to manage the complexities of business aligned IT architectures with detailed examples and industry cases

- Outlines a step-by-step design process using proven patterns to address complex business/ technical scenarios

- Integrates SOA, BPM, and EDA into practical patterns promoting SOA 2.0

Describing how to synchronize parallel enterprise processes, the authors explain how to cope with the architectural and design decisions you are likely to encounter when designing and implementing process-driven SOA systems. The decisions are described in the form of software patterns to provide you with a practical guideline for addressing key problems using time-tested solutions.
