Hi all, we are interested in using Prefect for ETL jobs at my firm. These particular ETL jobs run daily, have strict deadlines, and are considered critical for our business. So with that, I have some questions around the reliability of prefect server. Essentially, how can we avoid Prefect server being a single point of failure for the orchestration of flows? I appreciate there's probably a lot of approaches here, but as a scenario, let's suppose our server running prefect server had a hardware failure during a critical period - what could we do to mitigate this?
