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

Remote debugging in the cloud


The remote debugging of a Function App can be helpful if the function experiences an issue only after deployment. To debug the function in Azure, you can attach the debugger to the Function App. This will allow you to step through the deployed function in Visual Studio.

To perform remote debugging, execute the following steps:

  1. First, we need to change two settings in Visual Studio to enable remote debugging. In Visual Studio, navigate to Tools -> Options -> Debugging, and then deselect the Enable Just My Code and Require source files to exactly match the original version options as shown in the following screenshot:
  1. In Visual Studio, navigate to View -> Cloud Explorer.
  2. Navigate to your subscription -> App Services -> TextEvaluation.
  3. Right-click on the service and choose Attach Debugger.
  4. After the debug symbols load, you will be able to set up breakpoints and step through the function. To hit a breakpoint, you will need to trigger the function execution...
