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.

Client-side bootstrap approaches

In the example solution described previously, all of the applications must hold the network location of the configuration server. The network location of service discovery is stored there as a property. At this point, we are confronted with an interesting problem to discuss. We could ask whether our microservices should be aware of the Config Server's network address. In previous discussions, we have agreed that the main place all the service’s network locations should be kept is the service discovery server. The configuration server is also a Spring Boot application like other microservices, so logically it should register itself with Eureka to enable the automated discovery mechanism for other services that have to fetch data from the Spring Cloud Config Server. This in turn requires placing the service discovery connection settings in bootstrap.yml instead of the property.

Choosing between these two different approaches is one of...
