What does the ideal deployment process look like for this scenario?
blender: "Unscheduled downtime of more than a couple minutes is unacceptable any time."Sounds like HA should be your #1 priority. DRBD + Heartbeat is a one solution but non-trivial to setup. There are some high-end hosting providers (BlueLock, Terremark) that offer VMWare HA configurations.Sounds like VCS should be #2 - checkout cvsdude.com (no affiliation but we've used them and they're good)Cheers
