Overview of this book

Do you want to build and deploy microservices but are unsure where to begin? Check out the fully updated 2025 edition of Microservices with Spring Boot and Spring Cloud. Drawing from Magnus’ decades of experience, you’ll start with simple microservices and progress to complex distributed applications, learning essential functionality and deploying microservices using Kubernetes and Istio along the way. This book covers Java 24, Spring Boot 3.5, and Spring Cloud 2025, featuring updated code examples and replacing deprecated APIs. You’ll get a clear understanding of Spring’s Ahead of Time (AOT) module, observability, distributed tracing, and Helm for Kubernetes packaging. The chapters show you how to use Docker Compose to run microservices with databases and messaging services and deploy microservices on Kubernetes with Istio. You’ll also explore persistence, resilience, reactive microservices, and API documentation with OpenAPI, as well as learn service discovery with Netflix Eureka, edge servers with Spring Cloud Gateway, and monitoring with Prometheus, Grafana, and the EFK stack. By the end of this book, you’ll be able to confidently build scalable microservices using Spring Boot and Spring Cloud.

Improving Resilience Using Resilience4j

In this chapter, we will learn how to use Resilience4j to make our microservices more resilient – that is, how to mitigate and recover from errors. As we already discussed in Chapter 1, Introduction to Microservices, in the Circuit breaker section, and Chapter 8, Introduction to Spring Cloud, in the Using Resilience4j for improved resilience section, a circuit breaker can be used to minimize the damage that a slow or unresponsive downstream microservice can cause in a large-scale system landscape of synchronously communicating microservices. We will see how the circuit breaker in Resilience4j can be used together with a time limiter and retry mechanism to prevent two of the most common error situations:

  • Microservices that start to respond slowly or not at all
  • Requests that randomly fail from time to time, for example, due to temporary network problems

The following topics will be covered in this chapter:
