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.

Messaging patterns used in distributed systems

As we saw in the previous chapter, distributed system designers use different networking topologies to interconnect systems, and most of those topologies are still used heavily in the technology industry. Network topology defines the layout of communication within the platform and the actual communication pattern; the protocols are not well defined there. In this chapter, we will discuss the communication that occurs within a distributed system.

Distributed system designers have produced different approaches to communicating between systems. These patterns include the following:

  • Remote procedure calls (RPC) versus shared resources
  • Synchronous versus asynchronous (client-server versus pub-sub)
  • Orchestration versus choreography

Let's look at the preceding approaches in more detail so that we can use them when designing communication patterns for a microservice architecture, which is another distributed system...
