However, I suspect you have OpenStack so you can have many small apps with a few instances, and thus you'll find many of them can benefit from a good solid object store. _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
