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.

Best logging practices for microservices

One of the most important best practices for dealing with logging is to trace all the incoming requests and outgoing responses. Maybe it seems obvious to you, but I have seen a couple of applications that did not comply with that requirement. If you meet this demand, there is one consequence that occurs with microservices-based architecture. The overall number of logs in your system increases compared to monolithic applications, where there is no messaging. This, in turn, requires us to pay even more attention to logging than before. We should do our best to generate as little information as possible, even though this information can tell us much about the situation. How do we achieve this? First of all, it is good to have the same log message format across all the microservices. For example, let's consider how to print variables in the application logs. I suggest you use the JSON notation in view of the fact that, usually, messages exchanged between...
