Azure Serverless Computing Cookbook - Third Edition

By: Praveen Kumar Sreeram

Overview of this book

This third edition of Azure Serverless Computing Cookbook guides you through the development of a basic back-end web API that performs simple operations, helping you understand how to persist data in Azure Storage services. You'll cover the integration of Azure Functions with other cloud services, such as notifications (SendGrid and Twilio), Cognitive Services (computer vision), and Logic Apps, to build simple workflow-based applications. With the help of this book, you'll be able to leverage Visual Studio tools to develop, build, test, and deploy Azure functions quickly. It also covers a variety of tools and methods for testing the functionality of Azure functions locally in the developer's workstation and in the cloud environment. Once you're familiar with the core features, you'll explore advanced concepts such as durable functions, starting with a "hello world" example, and learn about the scalable bulk upload use case, which uses durable function patterns, function chaining, and fan-out/fan-in. By the end of this Azure book, you'll have gained the knowledge and practical experience needed to be able to create and deploy Azure applications on serverless architectures efficiently.

Connecting to the Azure Storage from Visual Studio

In both of the previous recipes, you learned how to create and execute Azure Functions in a local environment. You triggered the functions from a local browser. However, in this recipe, you'll learn how to trigger an Azure function in your local environment when an event occurs in Azure. For example, when a new blob is created in an Azure storage account, we can have our function triggered on our local machine. This helps developers to test their applications upfront, before deploying them to the production environment.

Getting ready

Perform the following steps:

  • Create a storage account, and then a blob container named cookbookfiles, in Azure.
  • Install Microsoft Azure Storage Explorer from http://storageexplorer.com/.

How to do it...

In this section, you'll learn how to create a blob trigger that will trigger as soon as a blob is created in the storage account.
