Introduction

Every software application needs backend components that are responsible for taking care of the business logic and storing the data into some kind of storage such as database, filesystem, and so on. Each of these backend components could be developed using different technologies. Azure serverless technology also allows us to develop these backend APIs using Azure Functions.

Azure Functions provide many out-of-the-box templates that solves most of the common problems such as connecting to storage, building Web APIs, cropping the images, and so on. In this chapter, we will learn how to use these built-in templates. Along with learning the concepts related to Azure serverless computing, we will also try to implement a solution to a basic domain problem of creating components required for any organization to manage the internal employee information.

Below is a simple diagram that helps you understand what we will be going to achieve in this chapter:
