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.

Reading the app settings in your Azure Function

Once you configure your function app, you need to read the values stored in it.

Reading the values contained in the settings is automatic for triggers and bindings in the sense that the infrastructure provides the INameResolver interface used by them to access these values. For more information, refer to Chapter 2, Customizing Your Azure Functions.

However, sometimes you need to access the setting values from the code of your Azure Functions. To do this, you can use the configuration support provided by .NET Core.

The following extension method extends the ExecutionContext class to provide the values configured in the settings:

public static IEnumerable<KeyValuePair<string, string>> GetConfigurations(this ExecutionContext context)
if (context == null)
throw new NullReferenceException(nameof(context));
