Introduction

Every software application needs backend components that are responsible for taking care of business logic and storing the data in some kind of storage, such as databases and filesystems. 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 solve most common problems, such as connecting to storage, building Web APIs, and cropping images. In this chapter, we will learn how to use these built-in templates. Apart from learning about the concepts related to Azure serverless computing, we will also try to implement a solution to a basic domain problem of creating components, which is required for any organization who wants to manage internal employee information.

The following is a simple diagram that will help you understand what we will achieve in this chapter:
