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.

Debugging Azure Function hosted in Azure using Visual Studio

Once the basic setup of your Function creation is complete, the next step is to start working on developing the application as per your needs. Developers end up facing numerous technical issues that require tools to identify the root cause of the problem and fix it. These tools include debugging tools that help developers to step into each line of the code to view the values of the variables and objects and get a detailed view of the exceptions.

Getting ready

Download and install the Azure CLI (if these tools are not installed, Visual Studio will automatically download them when you run your functions from Visual Studio).

How to do it...

In this section, you'll learn how to configure and debug an Azure function in a local development environment within Visual Studio.

Perform the following steps:

  1. In the previous recipe, you created the HTTP trigger function using Visual Studio. Let's build...
