For a customer of ours we're managing a dedicated cluster with about 
10.000.000 Hits/Day hitting the webservers (currently 5 running 
Loadbalancing is done by a set of reverse squid's acting as caches for 
static content also (round about 70% of all hits are handled by squid 
without bothering the webservers).

We're quite happy with this setup at the moment. By now Database-Load is 
handled by only one DB-Server (with manual failover).

In my opinion this is only a matter of negotiation with your hosting 
company - but sure this is dependent on how much control you want to 
have ;-)
