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.

How to do it…

Once we are done with development and have tested the apps thoroughly in our local environment, it's time to deploy them to Azure. There may be instances where we encounter issues after deploying an application to Azure, mainly due to incompatibility with the environment. For example, a developer might have missed out on creating app settings in the app. With a missing configuration key, the end product may not only produce faults, but it may also prove difficult to troubleshoot the error. In this recipe, you'll learn not only how to view real-time logs, but also how to use the Diagnose and solve problems feature.

Viewing real-time application logs

In this section, we are going to view the real-time application logs using the Logs feature provided by the Azure portal. We can achieve it by performing the following steps:

  1. Navigate to Platform features of the function app and click on the Log Streaming button, where the Application logs...
