A massive benefit of building serverless, event-driven applications on top of Azure Functions or AWS Lambda is the ability to rapidly scale in and out in response to demand. To best use this serverless compute, we need to break down our applications into short-lived functions that react to events.
The challenge is: how can we coorinate these event flows into complete stateful applications?
This talk will introduce and demonstrate one approach: Orchestration using State Machines. Two state machine options will be presented and contrasted:
- Using the Orchestration and State Machine features in Mass Transit - an open souce framework for .NET
- Using AWS Step functions

The code samples will be in .NET but we'll introduce plenty of concepts along the way that will be useful to any developer in any language!
