Azure Functions

Azure Functions is a serverless compute service that runs event-driven code without managing infrastructure. Its unique binding system connects to Azure services declaratively, and Durable Functions enable complex stateful workflows.

Core Concepts

• Trigger — what causes a function to run (HTTP, timer, queue, blob, etc.)
• Input Binding — declaratively read data from a service when function runs
• Output Binding — declaratively write data to a service after function runs
• Function App — a container for one or more functions sharing configuration
• Hosting Plan — Consumption (pay-per-execution), Premium, or Dedicated
• Durable Functions — extension for stateful orchestrations and workflows
