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 makes it easy to develop JVM applications for the cloud. In this book, we introduce you to Spring Cloud and help you master its features.

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 the features of the Feign client. We then dive into advanced topics where you will learn to implement distributed tracing solutions for Spring Cloud and build message-driven microservice architectures.

This book appeals to developers keen to take advantage of Spring Cloud, an open source library which helps developers quickly build distributed systems. Knowledge of Java and Spring Framework will be helpful, but no prior exposure to Spring Cloud is required.
