⚡Azure Functions

NEW

Azure Functions is an event-driven serverless compute platform that runs code without provisioning or managing servers.

DESCRIPTION

Azure Functions enables developers to execute code in response to events using a serverless model. It integrates with triggers and bindings for services like HTTP, timers, queues, and Event Hub. The platform automatically scales, offers a choice of hosting plans, and supports multiple languages. Durable Functions adds orchestration capabilities for stateful workflows. It reduces operational overhead by abstracting infrastructure and billing per execution.
