Mastering Spring Cloud

By: Piotr Mińkowski

Overview of this book

Developing, deploying, and operating cloud applications should be as easy as local applications. This should be the governing principle behind any cloud platform, library, or tool. Spring Cloud–an open-source library–makes it easy to develop JVM applications for the cloud. In this book, you will be introduced to Spring Cloud and will master its features from the application developer's point of view. This book begins by introducing you to microservices for Spring and the available feature set in Spring Cloud. You will learn to configure the Spring Cloud server and run the Eureka server to enable service registration and discovery. Then you will learn about techniques related to load balancing and circuit breaking and utilize all features of the Feign client. The book now delves into advanced topics where you will learn to implement distributed tracing solutions for Spring Cloud and build message-driven microservice architectures. Before running an application on Docker container s, you will master testing and securing techniques with Spring Cloud.

Running Eureka on the server side

Running the Eureka Server within a Spring Boot application is not a difficult task. Let's take a look at how this can be done:

  1. First, the right dependency has to be included to our project. Obviously, we will use a starter for that:
  1. Eureka Server should also be enabled on the main application class:
public class DiscoveryApplication {

    public static void main(String[] args) {
        new SpringApplicationBuilder(DiscoveryApplication.class).web(true).run(args);

  1. It is interesting that together with the server starter, client's dependencies are also included. They can be useful for us, but only when launching Eureka in high availability mode with peer-to-peer communication between discovery instances. When running a standalone instance...
