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.

Discovery and distributed configuration

Service discovery and distributed configuration management are vital parts of the microservices architecture. The technical implementation of these two different mechanisms is pretty similar. It comes down to storing parameters under specific keys in a flexible key-value storage. Actually, there are several interesting solutions available on the market which provide both of these functionalities. Spring Cloud integrates with the most popular of them. But there is also one exception where Spring Cloud has its own implementation created only for distributed configuration. This feature is available under the Spring Cloud Config project. In contrast, Spring Cloud does not provide its own implementation for service registration and discovery.

As usual, we can divide this project into the server and client-side support. The server is the one, central place where all of the external properties for applications are managed across all of the environments. Configuration...
