Introduction

Traditionally, developers wrote applications in a monolithic manner. This means one single executable that is broken up into components via classes and so on. Monolithic applications require a great deal of testing, and deployment is tedious due to the bulkiness of the monolithic application. Even though you might have multiple developer teams, they all need to have a solid understanding of the application as a whole.

Microservices is a technology that aims to address the issues surrounding monolithic applications and the traditional way of developing applications. With microservices, you can break the application into smaller bits (services) that can function on their own without being dependent on any of the other services. These smaller services can be stateless or stateful and are also smaller in scale in terms of functionality, making them easier to develop, test, and deploy. You can also version each microservice independently from the others. If one microservice is receiving...
