My understanding is this not true, only when the instance permanently fails and is moved.

  stop or hibernate kills it. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-store-lifetime.html https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance...

    Yeah, so restart does not. Which means you can count on it about as much as a server of your own, if you could not repair the server. I know a database company that uses instance storage as the primary storage. It’s common.

      Wasn't aware, interesting. I did consider it in the past as well, but the reliability aspect made me consider this as a moonshot rather than anything practical. Kind of weirdly validating to know there are (supposedly) database providers using it. That said, a good bit of our environments are scheduled, so it still wouldn't be an option there without hacks (e.g. doing a compressed blockwise dump before shutting down and then a blockwise flash on startup).

        I would take a logical dump on shutdown and the restore that rather. You’d need a backup and restore process anyway, so that path has to exist either way. It’s kind of like a full vacuum, so has some benefits too. The NDA prevents me from saying which database company, but it’s a major provider of cloud managed databases across clouds.
