I thought this would have mentioned live migration, which honestly solves a major pain point in aws.

  it does not. if you need live migration your software is poorly engineered. the only use case for this is a legacy app that you cannot move away from - but in that case i doubt you’re in the cloud

    Imagine you running large database workload and AWS say you need reboot because underlying hardware start having issue. Live migration can help you in that case.

      1. use RDS 2. if you want to run your own you’d better know how HA setups work and you can lose at least a machine at ANY point in time (not just when AWS warns you the hardware is failing)

        RDS is a joke unless you use aurora. Necessary downtime for a database upgrade? Try again Amazon.

          what engine are you using? is it in an multi-AZ setup?
          • tbrock 6y ago
            Postgres, yes, of course

    I don’t disagree, but as much as this is said manny legacy workloads handle this poorly, and many new workload do just as badly.
