Serverless computing in Azure with .NET

Overview of this book

Serverless architecture allows you to build and run applications and services without having to manage the infrastructure. Many companies have started adopting serverless architecture for their applications to save cost and improve scalability. This book will be your companion in designing Serverless architecture for your applications using the .NET runtime, with Microsoft Azure as the cloud service provider. You will begin by understanding the concepts of Serverless architecture, its advantages and disadvantages. You will then set up the Azure environment and build a basic application using a sample text sentiment evaluation function. From here, you will be shown how to run services in a Serverless environment. We will cover the integration with other Azure and 3rd party services such as Azure Service Bus, as well as configuring dependencies on NuGet libraries, among other topics. After this, you will learn about debugging and testing your Azure functions, and then automating deployment from source control. Securing your application and monitoring its health will follow from there, and then in the final part of the book, you will learn how to Design for High Availability, Disaster Recovery and Scale, as well as how to take advantage of the cloud pay-as-you-go model to design cost-effective services. We will finish off with explaining how azure functions scale up against AWS Lambda, Azure Web Jobs, and Azure Batch compare to other types of compute-on-demand services. Whether you’ve been working with Azure for a while, or you’re just getting started, by the end of the book you will have all the information you need to set up and deploy applications to the Azure Serverless Computing environment.

Preface

Debugging the functions locally


The precompiled functions that run locally in Visual Studio 2017 provide the exact same debugging experience as any other .NET application including breakpoints, local variables, call stack, and more. The Visual Studio 2017 function tools also bring full IntelliSense and the ability to unit test the functions.

When running C# script-based functions, or other script language based functions online, the debugging experience may vary. Still, with C# script-based functions, it is possible to attach a Visual Studio debugger to a function deployed online.

In this section, we will focus on working with class-library-based precompiled functions in Visual Studio.

As mentioned in the introduction to this chapter, debugging, typically, starts with execution testing, which involves triggering the function under particular conditions. With Azure Functions, the execution testing approach is highly dependent on the function trigger type. Some functions are very easy to trigger...
