Practical Microservices

Overview of this book

<p>A microservice architecture helps you build your application as a suite of different services. This approach has been widely adopted as it helps to easily scale up your application with reduced dependencies. This way if a part of your application is corrupted, it can be fixed easily thereby eliminating the possibility of completely shutting down your software. This book will teach you how to leverage Java to build scalable microservices. You will learn the fundamentals of this architecture and how to efficiently implement it practically.</p> <p>We start off with a brief introduction to the microservice architecture and how it fares with the other architectures. The book dives deep into essential microservice components and how to set up seamless communication between two microservice end points. You will create an effective data model and learn different ways to test and deploy a microservices. You will also learn the best way to migrate your software from a monolith to a microservice architecture.</p> <p>Finishing off with monitoring, scaling and troubleshooting, this book will set a solid foundation for you to start implementing microservices.</p>

Preface

Chapter 3. Communication between Microservices Endpoints

In the last chapter, you learned about service discovery and the API Gateway pattern. The chapter explained how to find microservices, but it would be interesting to dig into the detail of how microservices actually communicate at the protocol level. There are many options available for these interservice communication patterns. Once you decide which pattern suits your requirements, you will learn about the protocol that will be used. It could be SOAP, REST, XML-RPC, and so on. In this chapter, we will go through the major pattern found in interservice microservices communication. We will also go through an example of one of these patterns.

In this chapter, we will cover the following topics:

  • How should microservices communicate with each other?
  • Orchestration versus choreography
  • Synchronous versus asynchronous communication
  • Use of message brokers for event-driven microservices
  • Development of a financial microservice
