This was something like our original design:

                          ------------
                         | WWW Server |
                          ------------
                                 |
                                 |
  ------------  TCP/IP  ---------------------  TCP/IP   -----------------
 |  DB server |--------| Application server  |---------| Analysis Server |
  ------------          ---------------------           -----------------

The idea being the WWW server would just handle HTTP requests, and
return data to the user. The 'Application Server' would farm out any
jobs to the DB server or the Analysis server, compile the data and
send it back to the WWW server. That way we could easily implement
queuing on the App server if we wanted. Also, you could make the
Analysis server be a big beefy SMP box, likewise the DB server. You
could also have the WWW on one side of a firewall and the others
behind the firewall.
