Designing Production Microservices with Spring Boot 4: Build Scalable Java Services with Spring Cloud, PostgreSQL, Security, Kafka, Docker, Kubernetes, Testing, and Observability (en Inglés)
Reseña del libro "Designing Production Microservices with Spring Boot 4: Build Scalable Java Services with Spring Cloud, PostgreSQL, Security, Kafka, Docker, Kubernetes, Testing, and Observability (en Inglés)"
Build microservices that are ready for production—not just impressive in a diagram. Designing a microservices system is relatively easy. Designing one that can survive real traffic, network failures, database contention, deployment changes, security threats, and operational incidents is a different challenge. Designing Production Microservices with Spring Boot 4 is a practical guide to building scalable, resilient, and maintainable Java microservices using the modern Spring ecosystem. Rather than presenting disconnected examples, the book develops Northstar, a realistic commerce platform, throughout the chapters. You will see how architectural decisions evolve as the system introduces independent services, service-owned databases, synchronous communication, event-driven workflows, security, containers, Kubernetes, testing, observability, and production operations. Inside, you'll learn how to: Design effective service boundaries and domain ownership Build production-grade services with Spring Boot 4 and Java 21 Manage service-owned data with PostgreSQL, JPA, Flyway, transactions, and concurrency controls Implement reliable HTTP communication with timeouts, retries, circuit breakers, bulkheads, and idempotency Use Spring Cloud Gateway, configuration, and service discovery Build event-driven workflows with Apache Kafka Handle distributed consistency using sagas, transactional outbox, compensation, and reconciliation Secure services with Spring Security, OAuth 2.0, JWT, scopes, and service-to-service identity Test real infrastructure with JUnit and Testcontainers Build secure, reproducible Docker containers Deploy and operate services with Kubernetes Implement production observability with Actuator, Micrometer, OpenTelemetry, metrics, logs, traces, and SLOs Diagnose performance bottlenecks and plan for scaling and capacity Assemble the individual services into an operable production microservices platform This book focuses on the decisions that matter when systems fail: ownership, failure boundaries, idempotency, recovery, compatibility, security, deployment safety, and operational visibility. Whether you're a Java developer, Spring Boot engineer, backend developer, software architect, or platform engineer, this book provides a practical path from individual Spring services to a disciplined production microservices architecture. Move beyond basic REST APIs and learn how production microservices are actually designed, tested, deployed, observed, and operated.
