Ksplice provides updates without rebootsKsplice provides updates without rebootsPosted Jul 14, 2009 9:38 UTC (Tue) by jcm (subscriber, #18262)In reply to: Ksplice provides updates without reboots by NAR Parent article: Ksplice provides updates without reboots
Meanwhile, in the real world, most people don't have the kind of money required to do 100% hardware duplication and even then that might not be easily possible for certain applications. Ksplice is only a hack insomuch as anything is a hack until it's proven itself - Linux was a hack once.

if businesses need continuous availability they are going to have redundant hardware.
it may be 100% duplicate (1-1 replication), or it may be a n+x style cluster of machines, but in either case they will have the redundant hardware so that they can survive hardware failing.
there are some companies that try to save a little money and make the backup boxes less powerful than the primary boxes, but they almost never do this after they have actually _used_ their backup boxes (people really don't care that you had a system failure and are running on a backup, they just want their stuff to work, and work fast)

Telephony exchange systems based on Erlang are used on all 5 continents (as far as I know) - that's real enough to me. On the other hand, if the target audience of KSplice Inc. can't afford spare hardware, will they spend money on the services of KSplice Inc?
Also there's the "false sense of security" expression thrown around when a not perfect solution is given to a problem - ksplice could give "false sense of reliability".
