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 7. Advanced Load Balancing and Circuit Breakers

In this chapter, we will continue the subject discussed in the previous chapter, inter-service communication. We will extend it to more advanced samples of load balancing, timeouts, and circuit breaking. 

Spring Cloud provides features that make implementation of communication between microservices nice and simple. However, we must not forget that the major difficulties we would face with such communication concern the processing time of the systems involved. If you have many microservices in your system, one of the first issues you need to deal with is the problem of latency. In this chapter, I would like to discuss a few Spring Cloud features that help us to avoid latency problems that are caused by many hops between services when processing a single input request, slow responses from several services, or a temporary unavailability of services. There are several strategies for dealing with partial failures. These include setting network...
