Overview of this book

Building a scalable microservices platform that caters to business demands is critical to the success of that platform. In a microservices architecture, inter-service communication becomes a bottleneck when the platform scales. This book provides a reference architecture along with a practical example of how to implement it for building microservices-based platforms with NATS as the messaging backbone for inter-service communication. In Designing Microservices Platforms with NATS, you’ll learn how to build a scalable and manageable microservices platform with NATS. The book starts by introducing concepts relating to microservices architecture, inter-service communication, messaging backbones, and the basics of NATS messaging. You’ll be introduced to a reference architecture that uses these concepts to build a scalable microservices platform and guided through its implementation. Later, the book touches on important aspects of platform securing and monitoring with the help of the reference implementation. Finally, the book concludes with a chapter on best practices to follow when integrating with existing platforms and the future direction of microservices architecture and NATS messaging as a whole. By the end of this microservices book, you’ll have developed the skills to design and implement microservices platforms with NATS.

Chapter 4: How to Use NATS in a Microservice Architecture

In the first part of this book, we discussed the evolution of distributed systems, the microservice architecture, messaging technologies, and NATS messaging in detail as separate topics. In this second part of this book, we will start by using what we learned previously to design an effective microservice architecture by exploring these topics further and the correlation among them in detail.

As we discussed in Chapter 2, Why Is Messaging Important in the Microservice Architecture?, microservice architecture-based platforms have two main message flows called North-South traffic and East-West traffic. Sometimes, East-West traffic is also called inter-service communication in a microservice architecture. In this chapter, we will discuss these messaging flows in detail and how NATS can be used for inter-service communication within the microservice architecture. We are going to cover the following main topics in this chapter...
