Overview of this book

Microsoft Azure is currently one of the fastest growing public cloud service providers thanks to its sophisticated set of services for building fault-tolerant and scalable cloud-based applications. This second edition of Azure for Developers will take you on a journey through the various PaaS services available in Azure, including Azure App Service, Azure Functions, and Azure SQL Databases, showing you how to build a complete and reliable system with ease. Throughout the book, you’ll discover ways to enhance your skills when building cloud-based solutions leveraging different SQL/NoSQL databases, serverless and messaging components, containerized solutions, and even search engines such as Azure Cognitive Search. That’s not all!! The book also covers more advanced scenarios such as scalability best practices, serving static content with Azure CDN, and distributing loads with Azure Traffic Manager, Azure Application Gateway, and Azure Front Door. By the end of this Azure book, you’ll be able to build modern applications on the Azure cloud using the most popular and promising technologies to make your solutions reliable, stable, and efficient.

Creating a function

We discussed the overall serverless approach and went through local configuration to make sure that we have some basic understandings of what Azure Functions is and how we can start working with it. In the remainder of this chapter, I will show you what exactly this service offers and how to work with it on daily basis. This will enable you to start developing full projects with Azure Functions—from the simplest to the most advanced ones.

Using Visual Studio Code

In the previous section, you created a function using a wizard in Visual Studio. If you go back to this project and open its file, you will see some common code, which is always created with this template:

using System.Collections.Generic;
using System.Net;
using Microsoft.Azure.Functions.Worker;
using Microsoft.Azure.Functions.Worker.Http;
using Microsoft.Extensions.Logging;
namespace Company.Function
    public static class HttpTrigger1
