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.

Administrative access


Part of any security conversation is configuring developer and administrator access to the application itself. In the next section, we will discuss how to configure administrative access to our Azure resources.

Role-based access control

The Azure Portal allows for Role-based access control (RBAC). RBAC allows for granular access to the Azure resources.

Azure RBAC accepts the following two types of accounts:

  • Azure Active Directory accounts. Using AAD, you can grant access to users or groups from the default AAD tenant of your subscription.
  • Microsoft accounts. When using Microsoft accounts, you can grant access to any email that has been set up as a Microsoft account.

Note

If your environment is fully automated, and your application is deployed by a CI/CD pipeline, you may consider limiting administrator access to the application to the bear minimum, to prevent configuration drift.

You can configure user access through PowerShell, CLI, REST API, or the Azure Portal. To configure...
