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.

Performance testing

We still have one last type of automated test to discuss. It has already beenmentioned at the beginning of the chapter. I am, of course, talking about performance tests. There are some really interesting tools and frameworks that help you to create and run this kind of test. There is a large choice of instruments, especially if we are talking about HTTP API tests. I wouldn't like to discuss all of them, but I will talk about one framework that might be helpful. It's Gatling. Let's take a closer look at it.


Gatling is an open source performance testing tool written in Scala. It allows you to develop the tests in an easily readable and writable domain-specific language (DSL). It stands out from the competition by generating comprehensive, graphical load reports illustrating all the metrics collected during a test case. There are plugins available for integrating Gatling with Gradle, Maven, and Jenkins.
