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.

In this chapter, I have guided you through the main features of two Spring Cloud projects—Consul and Zookeeper. I haven't focused only on Spring Cloud functionalities, but have also given you the instructions on how to start, configure, and maintain instances of its tools. We have discussed even more advanced scenarios, such as setting up a cluster consisting of numerous members using Docker. There, you had a chance to see the true power of Docker as a development tool. It allowed us to initialize a cluster that consists of three members just by using three simple commands, without any additional configuration.

Consul seems to be an important alternative to Eureka as a discovery server when using Spring Cloud. I cannot say the same about Zookeeper. As you have probably noticed, I have written much more about Consul than Zookeeper. Also, Spring Cloud treats Zookeeper as a second choice. It still does not have a zoning mechanism or watching capability for configuration changes that...
