For scaling tips, check he presentations by Michael J. Radwin 
http://public.yahoo.com/~radwin/

Fault tolerance can be achieved using commodity hardware and free (as in 
speech) software. Some tips
- set up replication for your mysql databases
- load balance your reads between your db master and slave
- store your session data in a database (so that if one machine fails, 
the other can take over -- see my point above about replication)
- work out a failover strategy and test it rigorously. Don't depend on 
DNS magic for failover.
