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.

Software testing


Software testing is the process of evaluating the quality of a software product.

Most software products are complex, and can be looked at from a number of different perspectives. While it is required that the software product executes correctly, this is not sufficient for it to be considered a quality product. Drawbacks such as slow speed of execution or poor usability can prevent a perfectly correct application from being successfully delivered to its consumers. Thus, it is important for the testing procedures to cover more than just code correctness.

There are more testing types and approaches than this book can attempt to cover, and the number of tests that can be written and executed is practically infinite. As you will see from reading the next few pages, software testing can be more of an art than a science. Even the best testing approaches have major flaws, and 100% correctness verification is, actually, impossible. This is due to the fact that even the simplest of...
