The document introduces Azure Functions, a serverless computing service that allows developers to write code without managing servers. It discusses how Azure Functions handles automatic scaling and only charges for compute time used. The document also outlines the organization of functions apps, supported triggers, bindings, languages, and deployment tools. Finally, it provides an overview of Durable Functions for saving state and coordinating workflows across functions.
