Both provide serverless workflow orchestration. Which should you choose?
| Feature | AWS Step Functions | Azure Durable Functions |
|---|---|---|
| Definition | JSON (ASL) | Code (C#/JS/Python) |
| Pricing | Per State Transition | Per Execution (Function billing) |
| Max Duration | 1 year (Standard) | Unlimited |
| Human Approval | Built-in | Use External Events |
My Take: If you prefer visual workflows and are heavily AWS, use Step Functions. If you want code-first and .NET, Durable Functions wins.
