[PLUG] Linux Database and Web server considerations

[Richard Langis]

Well, for the sake of reliability, you might want to split them up between 
machines.  Of course, it all depends on what kind of load you'll have, as well 
as what kind of hardware you'll have serving such demands.

What I, personally, would do is split the firewall/masq/router from the 
others, and make a dedicated NFS/DB/Web box.  This keeps your data one machine 
away from the DMZ.

Your mileage may vary, and of course I'm sure others on the list will have 
more varied responses.
