Deploying Node.js Microservices

The term microservices is used to describe applications that have been built based on 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 to adopting a microservice architecture. Separating...
