Designing Microservices Platforms with NATS

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.

What are the new developments in the NATS messaging technology?

The NATS server implementation has gone through several iterations within the past couple of years. In this book, we have used the latest version that is available at the time of writing, which is NATS 2.2. We have not covered all the features of NATS within this book since a separate book would be required to do that. One major change NATS has made with the version 2.2 release is the introduction of JetStream as the successor of the NATS streaming feature. We'll discuss the JetStream feature of NATS in detail in the following section.

JetStream

Throughout this book, we have discussed how to utilize an event-based messaging approach for interservice communication within a microservice-based application design. We used NATS as the event hub that exchanges events (messages) across services. A sequence of events that adhere to a common schema (format) is called an event stream. Unlike processing a single event...
