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

Configuring the development environment


In this part of the chapter, we will go through the configuration of the development environment for the Azure Function App project in Visual Studio.

When we create functions online in the Functions portal, we create C# script .csx based functions. C# script code files have certain features that differ from traditional C# code, which will be highlighted in the Appendix A, C# Script-Based Functions.

When we create functions in Visual Studio, we are developing "precompiled" functions. The functions are built in a traditional class-library project, and compiled into a library (DLL). The entire library is then published as a Function App, accompanied by a function.json file for each function.

Development in Visual Studio offers full access to IntelliSense, unit testing, and integration with source control repositories and continuous delivery tools, and thus is preferable to the online experience.
