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.

Introduction

Up to this point, you have learned how to develop and apply Azure functions, in addition to validating the functionality of these functions. This chapter will explore some of the popular ways of testing different Azure functions. This includes running tests of HTTP trigger functions using Postman, as well as using Azure Storage Explorer to test Azure blob triggers, queue triggers, and other storage service–related triggers.

You will also learn how to set up a test that checks the availability of your functions. This is done by continuously pinging the application endpoints on a predefined frequency from multiple locations.
