Overview of this book

Spring 5.0 is due to arrive with a myriad of new and exciting features that will change the way we’ve used the framework so far. This book will show you this evolution—from solving the problems of testable applications to building distributed applications on the cloud. The book begins with an insight into the new features in Spring 5.0 and shows you how to build an application using Spring MVC. You will realize how application architectures have evolved from monoliths to those built around microservices. You will then get a thorough understanding of how to build and extend microservices using Spring Boot. You will also understand how to build and deploy Cloud-Native microservices with Spring Cloud. The advanced features of Spring Boot will be illustrated through powerful examples. We will be introduced to a JVM language that’s quickly gaining popularity - Kotlin. Also, we will discuss how to set up a Kotlin project in Eclipse. By the end of the book, you will be equipped with the knowledge and best practices required to develop microservices with the Spring Framework.

Preface

Distributed tracing


In typical microservice architectures, there are a number of components involved. A few of them are listed here:

  • Different microservices
  • API Gateway
  • Naming server
  • Configuration server

A typical call may involve more than four or five components. These are the important questions to ask:

  • How can we debug issues?
  • How can we find out the root cause of a specific problem?

A typical solution is centralized logging with a dashboard. Have all microservice logs consolidated in one place and offer a dashboard on top of it.

Distributed tracing options

The following screenshot shows the options for distributed tracing on the Spring Initializr website:

In this example, we will use a combination of Spring Cloud Sleuth and Zipkin Server to implement Distributed Tracing.

Implementing Spring Cloud Sleuth and Zipkin

Spring Cloud Sleuth provides features to uniquely trace a service call across different microservice components. Zipkin is a distributed tracing system that's used to gather data needed...
