Azure Functions

Azure Functions is an event-driven serverless compute platform that scales automatically to handle everything from HTTP requests to complex background data processing.

Azure Functions eliminates infrastructure management by executing code only when specific triggers occur: think HTTP webhooks, timer-based cleanups, or new messages in an Azure Service Bus queue. You write logic in languages like C#, Python, or JavaScript, while the platform handles the scaling from zero to thousands of concurrent instances. With the Consumption plan, you only pay for the exact execution time and memory used (the first 1 million requests per month are free). It integrates natively with the broader Azure ecosystem through bindings, allowing you to read from Cosmos DB or write to Blob Storage with minimal boilerplate code.
