Spring Boot 4 Cloud-Native Engineering: A Practical, Project-Based Approach to Java Microservices, Spring Security, REST APIs, Docker, Kubernetes, and

By: Koele, Haider

Building a Spring Boot application is one thing. Building one that is secure, reliable, observable, scalable, and ready for production is where many developers start to feel overwhelmed.

Spring Boot 4 Cloud-Native Engineering is designed to make that transition clear and manageable. You do not need prior experience with Spring Boot, microservices, Docker, Kubernetes, distributed tracing, or cloud-native architecture. A basic working knowledge of Java is helpful, and every major concept is introduced progressively through practical, project-based examples.

Instead of overwhelming you with isolated features or unexplained configuration, this book shows how the pieces of a modern Java backend fit together. You will progressively build an order-processing system while learning how production-ready APIs, databases, security, resilience, distributed communication, testing, observability, performance, and deployment work as one complete engineering system.

Mistakes, failed tests, configuration problems, and debugging sessions are treated as normal parts of learning. Each working endpoint, secured resource, successful test, trace, container, and deployment becomes another practical step toward confidence.

Key Features

Practical, project-based Spring Boot 4 development

Production-focused REST API design and HTTP contracts

PostgreSQL, Spring Data JPA, Flyway, transactions, and performance

Spring Security with OAuth 2.0, JWT, authorization, and resource ownership

Timeouts, retries, circuit breakers, caching, and idempotency

Microservices, Kafka, event-driven architecture, sagas, and eventual consistency

Testing with Spring Boot, PostgreSQL, Testcontainers, security, and contracts

Actuator, Micrometer, Prometheus, OpenTelemetry, logs, metrics, and tracing

JVM performance, virtual threads, concurrency, and horizontal scaling

Docker, Kubernetes, CI/CD, autoscaling, graceful shutdown, and rollback

What You Will Learn

You will learn how to structure maintainable Spring Boot applications, build stable REST APIs, persist data safely, secure backend services, design resilient distributed workflows, test real production behavior, diagnose failures using observability, improve application performance, package services as containers, and deploy them confidently to Kubernetes.

Who This Book Is For

This book is ideal for Java developers, students, self-learners, and backend developers who understand basic Java but are new to Spring Boot 4 or production cloud-native engineering. It is especially useful if you can build an application locally but want to understand how professional backend systems are secured, tested, monitored, scaled, and deployed.
