Azure Functions: Serverless Done Right

azureserverlessarchitecture

Serverless computing eliminates infrastructure management. Azure Functions takes this further with deep Azure integration and flexible hosting options.

Trigger Types

Functions respond to events:

  • HTTP requests
  • Queue messages
  • Timer schedules
  • Blob storage changes
  • Event Grid events

Durable Functions

Orchestrate complex workflows:

[FunctionName("OrderWorkflow")]
public static async Task RunOrchestrator(
    [OrchestrationTrigger] IDurableOrchestrationContext context)
{
    await context.CallActivityAsync("ValidateOrder", order);
    await context.CallActivityAsync("ProcessPayment", order);
    await context.CallActivityAsync("ShipOrder", order);
}

Cold Start Mitigation

Premium plan keeps instances warm. For critical workloads, the trade-off is worth it.
