Bonanni M. Azure Durable Functions Succinctly 2022

Textbook in PDF format

Durable Functions is an Azure Functions extension that implements triggers and bindings that abstract and manage state persistence. Using Durable Functions, you can easily create stateful objects entirely managed by the extension. Azure Durable Functions Succinctly author Massimo Bonanni will take readers from a recap of Azure Functions through Durable entities so that you can determine if this technology is right for your needs.
Azure Functions is one of the most important serverless technologies proposed by Azure. Even though this book is not directly about standard Azure functions, it is fundamental to recap what an Azure function is. As we will see in the following chapters, Durable Functions is based on Azure Functions, so all the basic behavior is the same. An Azure function is literally a snippet of code that executes on a runtime called Azure Functions Runtime and can be written in several programming languages (C#, JavaScript, TypeScript, F#, Java, Python, PowerShell). Because Azure Functions is a serverless technology, every function is triggered by an event, and the component in the runtime with the responsibility to do that is called the trigger. An Azure function must have one and only one trigger.
