Message-driven systems are omnipresent in software, yet their key concepts and inner workings are generally not well understood. Software products can benefit in many ways from a purposeful application of message-driven architecture, CQRS, and Event Sourcing. One problem is that the three concepts often get poorly implemented, leading to more damage than benefits. This circumstance in turn contributes to the false conclusion that message-driven systems are inherently complex and offer little value to software products. As a result, developers and architects tend to favor synchronous and temporally coupled communication and integration, even for distributed systems. This book provides a definitive resource for building software products as message-driven systems and applying CQRS and Event Sourcing wherever useful. For a purposeful application, the book draws the connection to business and product concerns. For an expert technical understanding, the explanations go into depth and provide detailed implementation guidance. In essence, this is the book I would have liked to have available when starting my journey with message-driven systems. The chapters represent a curated collection of all fundamental and advanced concepts I picked up during my work and research. The book is relevant for all developers and architects who build software products. This includes entry-level developers who want to learn about message-driven systems and seasoned experts interested in advanced patterns. The chapters serve both as a practical course for learning and as a contemporary reference for concepts, styles, and patterns.
