Overview of this book

Application development has evolved from traditional monolithic app development to using serverless options and microservices. This book is designed to guide you through using Microsoft's Azure Functions to process data, integrate systems, and build simple APIs and microservices. You will discover how to apply serverless computing to speed up deployment and reduce downtime. You'll also explore Azure Functions, including its core functionalities and essential tools, along with understanding how to debug and even customize Azure Functions. In addition to this, the book will take you through how you can effectively implement DevOps and automation in your working environment. Toward the concluding chapters, you'll cover some quick tips, troubleshooting techniques, and real-world serverless use cases that will help you make the most of serverless computing.

Creating the Azure function app

The first step you have to take when you deploy your Azure Function is creating the host environment that keeps your function alive. This environment is a function app.

You can imagine the function app as the serverless view of an App Service: it hosts your code and gives you a bunch of features that you can use to deploy, monitor, and configure your Azure Function.

When you decide to create a function app, you need the following resources:

  • The function app itself.
  • A storage account that stores your code. This is mandatory because your code needs a place to be saved.
  • An Application Insight component. This isn't mandatory; you will need it only if you want to monitor your code. We will talk more deeply about monitoring in one of the following chapters.
  • A hosting plan. This is mandatory when you choose to host your function in a Premium plan...
