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.

Securing ISC

The security of ISC (East-West within a microservices architecture needs to complement the security that is applied to North-South communication. One major difference between the security of North-South communication and the security of East-West communication is that the former deals with external systems and applications while the latter deals with internal systems. That allows us to consider options for ISC other than North-South communication.

Given that we use the NATS messaging platform as the intermediate component for ISC, the security implementation will depend on the security capabilities offered by NATS. We discussed the security features available in NATS in Chapter 3, What Is NATS Messaging?, and Chapter 4, How to Use NATS in a Microservices Architecture?, in detail. Let's first discuss how those features fit into the overall microservices security aspect and then implement a couple of options with a few examples using our Out Patient Department ...
