Hi, the Pantheon stuff is awesome.  But putting a site with 7M unique
visitors, probably 75-100 Million page views per month, on a single virtual
web server, even an X-Large, is both very risky and limited if the site
get's even bigger.

A more appropriate approach for a site of that size is to build a cluster of
servers in a high availability configuration which provides more flexibility
to use various web scaling technologies.  You'll see that's an approach
taken with even moderately sized Drupal sites.  I'll be covering all of this
in quite a bit of detail in my presentation in 2.5 hours.

Cheers,
Kieran
