Azure Function Apps

function apps image

What is Azure Functions?

  • Event-driven, serverless compute platform that allows developers to run event-triggered code without having to explicitly provision or manage infrastructure
  • Helps developers focus on writing the codes without having to take care of scaling and managing the underlying infrastructure
  • Stateless, meaning they do not maintain state between executions, which makes them well-suited for handling individual tasks or responding to specific events

Key Features

  • Pay-per-use pricing model (very cheap)
  • Bring your own dependencies (NPM or NuGet)
  • Integrated security
  • Simplified integration
  • Flexible development
  • Open-source

How Function Apps work
Trigger(action) -> (Input) -> Code -> Output

Triggers and bindings

  • Blob storage, Cosmos DB, Event Grid, Event Hubs, HTTP & webhooks, MS Graph Excel tables, Mobile Apps, Table storage., etc.

Host Configuration

  • host.json metadata files contains global configuration options that affect all functions for the function app.
