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.

Azure WebJobs

Azure WebJobs are a part of Azure App Service, and run in the same compute “container” as your Web App, at no additional cost. WebJobs are intended to run background tasks for your Azure Web, API, or Mobile apps without the need to provision infrastructure.

The WebJobs SDK provides built-in integrations with commonly used services such as Azure Storage or Azure Service Bus, and it is extensible. WebJobs can be deployed to an Azure Web App without an actual Web frontend. With this approach, WebJobs can be used to run any scheduled or continuously executing background jobs.

WebJobs can run programs (.exe, .cmd, .jar, and more) or scripts (.ps1, .sh, .js, and more). A typical job is implemented as a console application or a script.

WebJobs can be triggered in the following three ways:

  • On-demand: This type of job can be triggered from the Azure Portal...
