Practical Microservices Architectural Patterns

Upgrade your distributed applications with microservices. This practical guide bridges core concepts and advanced patterns to help you build resilient, scalable and high performing microservices, whether you're transitioning from monolithic architectures or starting fresh with microservices.

Fully updated for Spring Boot 3 and Spring Cloud, The Second covers modern capabilities, like reactive programming, enhanced observability, advanced security and streamlined configuration management. Learn to solve common architectural challenges in cloud-native development, including service discovery, inter-service communication, distributed transactions, configuration management and fault tolerance mechanisms like retries, timeouts and circuit breakers. You'll also implement real-world patterns using powerful frameworks like Axon for event sourcing and command handling, and Atomikos for managing distributed transactions with XA protocols.

This book provides a hands-on introduction to building modern cloud-native applications from scratch, building up to in-depth discussions on advanced topics, such as CQRS and event-driven architecture.

What You Will Learn:

• Explore the latest features in Spring Boot 3 and Spring Cloud 2024
• Build and manage microservices with, routing, security and interservice communication
• Apply proven patterns for real-world microservices problems
• Design event-driven architectures and implement CQRS
• Enable service discovery, centralized configuration, and resilience with Spring Cloud
• Handle distributed transactions using XA, and Saga patterns
• Leverage Axon Framework for event sourcing and command handling
• Secure services with OAuth2.0 and JWT

• Learn best practices for testing, fault tolerance and observability
  Who This Book Is For

  Java developers and software architects who have a foundational understanding of distributed multi-threaded application architecture. No prior experience with Spring Boot or Spring Cloud is required.

  Teaches how to secure, monitor, and ensure resilience using OAuth 2.0 and observability practices Includes hands-on e-commerce example with CQRS, distributed transactions, and cloud deployment Explains how to build scalable microservices with Spring Boot, Spring Cloud, and event-driven design
