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.

Summary

In this chapter, we have seen how capabilities in Kubernetes can be used to simplify a microservice landscape, meaning that we reduce the number of supporting services to be developed and deployed together with the microservices. We have seen how Kubernetes ConfigMaps and Secrets can be used to replace the Spring Cloud Config Server and how a Kubernetes Ingress object can replace the Spring Cloud Gateway.

Using cert-manager allowed us to automatically provision certificates for HTTPS endpoints exposed by the Ingress controller, eliminating the need for manual and cumbersome work.

To verify that the source code of the microservices can run on other platforms (that is, isn’t locked into Kubernetes), we deployed the microservices using Docker Compose and ran the test-em-all.bash test script.

In the next chapter, we will be introduced to the concept of a service mesh and learn how a service mesh product, Istio, can be used to improve observability, security...
