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.
