Azure Durable Functions represented the last missing building block to code long running, stateful function orchestrations in a serverless environment. And now they are here! :-)
The new Orchestrator function allow you to do several new things that differentiates it from an ordinary, stateless function.
For example you can call and await other functions, save outputs, and then resume the local state that is never lost.
With Durable Functions we have the possibility to successfully model tricky backends for mobile apps and this is what we will see during this talk.
