Book Description

THIS BOOK IS OUTDATED: A new and updated version of this book is available. You can find the link further down on this page.

With a practical approach, you'll begin with simple microservices and progress to complex distributed applications. Learn essential functionality and deploy microservices using Kubernetes and Istio.

This book covers Java 17, Spring Boot 3, and Spring Cloud 2022. Java EE packages are replaced with the latest Jakarta EE packages. Code examples are updated and deprecated APIs have been replaced, providing the most up to date information. Gain knowledge of Spring's AOT module, observability, distributed tracing, and Helm 3 for Kubernetes packaging.

Start with Docker Compose to run microservices with databases and messaging services. Progress to deploying microservices on Kubernetes with Istio. Explore persistence, resilience, reactive microservices, and API documentation with OpenAPI. Learn service discovery with Netflix Eureka, edge servers with Spring Cloud Gateway, and monitoring with Prometheus, Grafana, and the EFK stack.

By the end, you'll build scalable microservices using Spring Boot and Spring Cloud.

What you will learn

• Build reactive microservices using Spring Boot
• Develop resilient and scalable microservices using Spring Cloud
• Use OAuth 2.1/OIDC and Spring Security to protect public APIs
• Implement Docker to bridge the gap between development, testing, and production
• Deploy and manage microservices with Kubernetes
• Apply Istio for improved security, observability, and traffic management
• Write and run automated microservice tests with JUnit, test containers, Gradle, and bash
• Use Spring AOT and GraalVM to native compile the microservices
• Use Micrometer Tracing for distributed tracing

Who this book is for

If you're a Java or Spring Boot developer learning how to build microservice landscapes from scratch, then this book is for you. To get started, you need some prior experience in building apps with Java or Spring Boot.
