+ 1 definitely. you really trust your hardware if you think so.. :-)
For what it's worth, I've succesfully used this setup several times:
- main web server (fine tuned apache, or better lighttpd/nginx if you
have enough experience)
- at least two servers for static files. you can balance them under a
subdomain or have more subdomains and switch users according to
location or whatever
- main db server (for writes) and 2+ replicated for reads. or if
you're brave enough, consider mysql_proxy.
- backup server to store everything you can (backups are never
enough). offsite, or with another provider. I've used often rsync.net
in some heavy traffic environment, we tend to use a pfsense.org box to
deal with vpn's, load balancing and global firewalls. really powerful,
and worth a look if it match your needs.
hope it helps
