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.

How can a microservice architecture with NATS be improved?

At the beginning of this chapter, we discussed the challenges that are inevitable when designing microservice-based applications with NATS. Then, we discussed some of the new developments happening in the microservice architecture domain and the NATS server technology. In this section, we are going to discuss how we can improve the proposed microservice architecture with NATS using some of these new developments.

Using JetStream for improved message guarantees and stream processing

While designing the OPD application in Chapter 6, A Practical Example of Microservices with NATS, we had not considered the possibility of losing messages due to the unavailability of one of the services. But in the real world, when designing an application for a domain such as healthcare, we need to pay extra attention to the message delivery guarantees. This will ensure that all the major events that we share across services such as patient...
