Mastering Azure Serverless Computing

By: Lorenzo Barbieri, Massimo Bonanni

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. By the end of this book, you will have gained the skills you need to develop and deliver cost-effective Azure serverless solutions.

Technical requirements

In this chapter, you will learn how to deploy and configure your Azure Functions on Azure environments. Before you learn this, though, you must learn about what Azure is, how it works, and how to use resources and their templates.

You will use the Azure Resource Manager templates (ARM templates) and PowerShell to prepare the environment and deploy the functions in this environment.

Another important task that you will perform when you put your Azure Functions in production is configuring them. In the second part of this chapter, you will learn how to configure your functions, the best places to put the configuration information, and how you can read it inside your code.
