Hi Brian,
well, i don't think there is one canonical solution to this problem. We use
basically everything of the technologies you mentioned above in one part of
our system or another. ;-) It depends e.g. on your setup, your load, your
customer requirements, your internal organisation..
Cheers,

we're
using a pool of identical kamailio load balancers in front of our
systems, requests are distributed to it by routing means or DNS. If one of
this system fails or needs to be removed out of the pool (e.g. for
maintenance) we just move its IP adress to one of the other active or spare
machines. For more planned maintenance you can of course also use DNS to
shift load from one machine to another.
