"Publisher-Subscriber Architecture"
"Publisher-Subscriber Architecture" is a comprehensive guide that explores the foundational principles, essential protocols, and advanced implementation strategies underpinning modern pub-sub systems. The book delves into architectural concepts such as decoupling, key design patterns—including Broker, Mediator, and Observer—and both synchronous and asynchronous communication models. By examining topology variations, service discovery mechanisms, and positioning pub-sub within the broader realm of reactive and event-driven architectures, readers are equipped with a deep understanding of the versatility and scalability inherent to publisher-subscriber patterns.
Moving beyond theory, the book provides practical insights into protocol selection, serialization formats, and network transport considerations. It details scalability and performance tuning—from broker architectures and subscriber load balancing to message ordering, state management, and benchmarking. The text further addresses robust concerns of reliability, consistency, and security, presenting real-world methods for implementing high-availability, delivery guarantees, authentication, encryption, multi-tenancy, and regulatory compliance in pub-sub deployments.
Tying these threads together, "Publisher-Subscriber Architecture" surveys the diverse landscape of open source and enterprise technologies, integration with microservices and cloud platforms, and the demands of contemporary use cases such as IoT, event-driven orchestration, and machine learning pipelines. With thorough coverage of monitoring, observability, operational best practices, and an insightful look ahead to emerging protocols and research frontiers, this book is an indispensable resource for architects, engineers, and researchers designing resilient, scalable, and future-proof event-driven systems.
