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.

Chapter 1. Introduction to Microservices

Microservices are one of the hottest trends to emerge in the IT world during the last few years. It is relatively easy to identify the most important reasons for their growing popularity. Both their advantages and disadvantages are well known, although what we describe as disadvantages can be easily solved using the right tools. The advantages that they offer include scalability, flexibility, and independent delivery; these are the reasons for its rapidly growing popularity. There are a few earlier IT trends that had some influence over this growth in the popularity of microservices. I'm referring to trends such as the usage of common cloud-based environments and the migration from relational databases to NoSQL.

Before discussing this at length, let's see the topics we will cover in this chapter:

  • Cloud-native development with Spring Cloud
  • The most important elements in microservices-based architecture
  • Models of interservice communication
  • Introduction to circuit breakers and fallback patterns
