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.

Messaging and integration

I have already mentioned messaging brokers and their usage for communication between your application and Zipkin server. Generally, Spring Cloud supports two types of communications via synchronous/asynchronous HTTP and with messaging brokers. The first project from this area is Spring Cloud Bus. It allows you to send broadcast events to applications informing them about state changes such as configuration property updates or other management commands. Actually, we might want to use starters for AMQP with a RabbitMQ broker or for Apache Kafka. As usual, we only need to include spring-cloud-starter-bus-amqp or spring-cloud-starter-bus-kafka to the dependency management and all other necessary operations are performed through auto-configuration. 

Spring Cloud Bus is a rather small project allowing you to use distributed messaging features for common operations such as broadcasting configuration change events. The right framework for building a system consisting of...
