Advanced Serverless Workflows with Durable Functions
summary
Shows how Azure Functions plus the Durable Functions extension manage stateful, long-running workflows by composing orchestrator and activity functions, timers and external events. Demonstrates a runnable “durable dungeon” game using the local storage emulator and Storage Explorer, with fan-out/fan-in, human approval timeouts, retries, checkpoint/replay and an HTML front end in vanilla JS. Notes performance targets (≈5 sequential activities/sec per instance, ≈100 fan‑outs/sec) and explains partitions, extended sessions and geo‑redundant storage; the demo runs end‑to‑end.
