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.

Host infrastructure


Host infrastructure security pertains to the configuration, management, and security of compute (virtual machines, containers, and so on) and storage. This includes access permissions management of the servers, as well as applying optimal configuration at the OS level, and keeping up to date with security patching. In the IaaS model, the shared responsibility of the client starts at securing the host infrastructure.

With the PaaS model, including serverless compute, the cloud provider accepts full responsibility of securing the host infrastructure.

This provides another significant advantage of moving to the public cloud, particularly, to the PaaS services and serverless compute.

Since host infrastructure security is handled by the platform, we will not discuss it further in this chapter. Once again, certain details on it can be acquired from Azure compliance reports, which can be found on the Azure Trust Center website https://azure.microsoft.com/en-us/support/trust-center...
