This assumes all application designers are doing this. Most web applications do this fairly well, but most enterprise applications do this very poorly. Hardware HA is useful for more than just poorly designed applications though. I have a cloud instance that runs my personal website. I don't want to pay for two (or more, realistically) instances just to ensure that if my host dies that my site will continue to run. My provider should automatically detect the hardware failure and re-launch my instance on another piece of hardware; it should also notify me that it happened, but that's a different story ;). - Ryan Lane _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
