in my enterprise world, production systems are fully redundant, and have
staging servers running identical software configurations. all upgrades
and upgrade procedures are tested on staging before being deployed in
production. quite often, the staging systems double as the Disaster
Recovery systems, but thats another story. virtually all production
systems either have a schedulable downtime (2am sunday morning?), or
support rolling upgrades with no downtime (such as our 24/7 factory
operations where downtime == no product).
personally, I'm very glad I work in development, where our informal SLA
is more like 9-9 5 days/week (developers like to work late).
