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 2: Why Is Messaging Important in the Microservice Architecture?

The microservice architecture operates in a decentralized manner where each function is executed by an independent microservice. At the same time, the success of the overall solution depends on the success of each service, as well as the collaboration among services. This demands a proper messaging framework to handle inter-service communication. Messaging is a method of communication between software components or applications. In a typical enterprise platform, there are two main flows of traffic, namely North-South traffic and East-West traffic. The North-South traffic represents the communication coming in and going out of a data center from external systems. In the context of microservices, we can replace the data center with a microservice-based platform. The East-West traffic represents the communication within the data center. For microservices, we can define East-West traffic as the communication within...
