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.

Additional features

Let's take a look at some other useful features of the Spring Cloud Config.

Fail on start and retry

Sometimes it doesn't make any sense to launch the application if the Config Server is unavailable. In this case, we would like to halt a client with an exception. To achieve this, we have to set the bootstrap configuration property to true. Such a radical solution is not always the desired behavior. If a Config Server is unreachable only occasionally, the better approach would be to keep trying to reconnect until it succeeds. The property still has to be equal totrue, but we would also need to add the spring-retrylibrary andspring-boot-starter-aopto the application classpath. The default behavior assumes to retry six times with an initial backoff interval of 1000 milliseconds. You may override these settings by using the*configuration properties.

The same as for the service discovery...
