Chapter 11: Deploying Node.js Microservices

The term microservices is used to describe applications that have been built on the basis of the microservice architecture paradigm. This architecture encourages larger applications to be built as a set of smaller modular applications, where each application focuses on one key concern. Microservice architectures are a contrast to the monolithic architectures of the past. Monolith is a term given to an application that handles many disparate concerns.

There are numerous benefits to adopting a microservice architecture. Ensuring that an application only serves one purpose means that the application can be optimized to best serve that purpose. Microservices help to decouple various parts of a system, which can result in easier debuggability if something goes wrong. Adopting a microservice architecture also enables you to scale different parts of the system independently.

There are not only technical benefits of adopting a microservice...
