Cool, thanks for the info! I wonder about the underlying instance's OS, though... in the past, for home servers, I've set up cron jobs to get OS updates and reboot, but that seems wrong for a web server I'd like to be always up. Maybe create a new instance, update the OS, install the app, switchover? Is there automation for this kind of thing?
