Azure Functions

Build and deploy serverless applications with Azure Functions. Covers function app creation, trigger and binding configuration, deployment strategies, real code examples in Python and Node.js, and production best practices.

When to Use

• You need event-driven compute that scales automatically to zero.
• You are building APIs, webhooks, or background processing pipelines.
• You want per-execution billing without managing servers.
• You need to respond to Azure service events (Blob Storage, Service Bus, Cosmos DB changes).
• You are implementing lightweight microservices or scheduled tasks.
