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.

Chapter 6. Communication Between Microservices

In the last two chapters, we discussed details related to very important elements in microservice architecture—service discovery and the configuration server. However, it is worth remembering that the main reason for their existence in the system is just to help in the management of the whole set of independent, standalone applications. One aspect of this management is communication between microservices. Here, a particularly important role is played by service discovery, which is responsible for storing and serving the network locations of all available applications. Of course, we may imagine our system architecture without a service discovery server. Such an example will also be presented in this chapter.

However, the most important components taking part in an inter-service communication are HTTP clients and client-side load balancers. In this chapter, we are going to focus just on them. 

The topics we will cover in this chapter include:
