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.

Other useful libraries

There are some important aspects surrounding microservices architecture, which can't be considered its core features, but are also very important. The first of them is security.


The big part of standard implementation for securing APIs with mechanisms such as OAuth2, JWT, or basic authentication is available in Spring Security and Spring Web projects. Spring Cloud Security uses those libraries to allow us to easily create systems that implement common patterns such as single sign-on and token relay. To enable security management for our application we should include the spring-cloud-starter-security starter.

Automated testing

The next important area in microservices development is automated testing. For microservices architecture, contact tests are growing in importance. Martin Fowler gave the following definition:

"An integration contract test is a test at the boundary of an external service verifying that it meets the contract expected by a consuming service...
