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 described the most important features of a Spring Cloud Config project. The same as for service discovery, we started from the basics, a simple use case on the client and server sides. We discussed the different backend repository types for a Config Server. I implemented the examples illustrating how to use filesystem, Git, and even third-party tools such as Vault as a repository for your property files. I put particular focus on interoperability with other components, such as service discovery or multiple instances of microservices within a larger system. Finally, I showed you how to reload an application's configuration without restart, based on WebHooks and a message broker. To conclude, after reading this chapter you should be able to use Spring Cloud Config as one element of your microservice-based architecture and take an advantage of its main features.

After we have discussed an implemetation of service discovery and configuration server with Spring...
