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.

Challenges of the proposed microservice architecture with NATS

In the previous chapters, we went through practical examples of implementing microservices with their scope and data while sharing information in a secured manner through the NATS messaging technology. In this section, we are going to discuss some of the areas that we need to pay extra attention to when building applications with the proposed architecture.

Message delivery guarantees and error handling

NATS is designed to offer simplicity and performance to users. These design principles can sometimes make things challenging for certain applications. The NATS core technology offers an at- most -once message delivery guarantee. In this mode, a message is delivered to a subscriber no more than one time. So, there is a possibility of message loss here. This mode of operation is suited for many practical applications, including the scenarios mentioned here:

  • Applications that use a request-reply-based communication...
