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.

Deploying Azure Functions in a container

You have now seen some of the major use cases for Azure Functions—in short, when developing a piece of code and deploying it in a serverless environment, where a developer or administrator doesn't need to worry about the provisioning and scaling of instances to host server-side applications.

Note

You can take advantage of all the features of serverless (for example, autoscaling) only when you create your function application by choosing the Consumption plan in the Hosting Plan drop-down menu.

By looking at the title of this recipe, you might already be wondering why and how deploying an Azure function to a Docker container will help. Yes, the combination of Azure Functions and Docker containers might not make sense, as we would lose all the serverless benefits (for example, autoscaling) of Azure Functions if we deployed to Docker.

However, there may be some customers whose existing workloads might be in a cloud (be it...
