Why Microservices are used?

With microservices, multiple teams work on independent services, enabling you to deploy more quickly — and pivot more easily when you need to. Development time is reduced, and your teams’ code will be more reusable. By decoupling services, you won’t have to operate on expensive machines.

What happens when an API is called?

Most web APIs sit between the application and the web server. The user initiates an API call that tells the application to do something, then the application will use an API to ask the web server to do something. The API is the middleman between the application and the web server, and the API call is the request.
