Introduction to microservices

Changing a few things in a big application is a constant pain for developers. Every time we make a small change in the code, we might have to deploy the whole application into servers, which is a time-consuming and tiring process, especially when we have multiple services, like accounting, reporting, user management, and so on. Microservices help us get rid of this pain. The main goal of microservices is to split up the application into services and deploy each service to our servers independently. By doing this, we provide loosely coupled processes in our application. Also, microservices can be deployed in the cloud to avoid service outage issues and provide nonstop services to consumers.

In microservices, each module or business section can be written as a separate service to provide continuous delivery and integration. These services are built to fulfill specific business requirements, and they are independently deployable by automating deployment infrastructure...
