I'm considering a scenario where a customer has two application
servers 1 of which is meant to be redundant and they would like to
automatically fail over and fail back in certain circumstances
(off-line backups, code updates etc) to get as close to 100% uptime as
possible. At this stage the customer tells me there is no data sharing
going on between the two servers - it's just two copies of application
What is the degree of difficulty associated with building one of these ?
How well does it work ?
Any gotchas I should be aware of ?
I guess right now I'm mainly trying to gauge how hard this might be to
do (and thus also to support) and how widely spread this feature is
used so I have a place to go if I have any questions. No-one down this
way has used this technology.
