it really depends on what your website needs; if it's just serving
static files you can go the easy solution (rotating DNS, rsync in a cron
job to distribute content changes, and either an IP-steal-when-crash or
a rapid take-out-of-DNS thing for availability). That scales really
well.

However if you have a really complex transaction based website with lots
of state on the server, then a more complex solution is needed
