Another question, which may be a rather naive one. What happens if the execution environment where a Prefect flow is deployed gets deleted? For example, an EC2 instance gets terminated for some reason. I'm guessing that because of the lack of a persistence layer, that flow is lost.

Hi Akash, I probably sound like a broken record to you but this sort of high availability is where a persistence layer becomes necessary (as you guessed); in Core alone, your flow is simply lost
