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.

Configuring your Azure Functions

The app settings for a function app are similar to the app settings you would configure for a website: in the app settings, you insert the global options that are valid for all of the functions contained in the function app.

When you develop an Azure Function, you can have local settings—that is, the settings you want to use only when you run your functions locally (for example, using the local storage emulator or a test key for a particular service)—and Azure settings—that is, the settings you want to run when you deploy your functions in a function app.

Moreover, you have settings that are related to the runtime (for example, the configured extensions, and the logger settings).

For the local settings, you can use a file called local.settings.json. This file is, generally, created by Azure Function Core Tools (or by Visual...
