exactly the point....without lots of carefully managed and well  
configured components, an app built on something like Rails won't be  
reliable when you get spiked.

The recommended approaches to scaling with rails do work, but there  
are _lots_ of parts to install and configure just so.  Companies like  
textdrive and the soon to be released railsbase are obviously hoping  
to cash in on solving this problem.  Within the next year or so, you  
should be able to host your Rails app on a grid like hosting system  
and draw from a well configured and managed "mega-host".  FYI, it  
looks as though the textdrive (maybe railsbase) folks will be running  
this new grid on Niagra servers.  I have no special inside knowledge,  
I just try to keep up with what info is available...but I"m pretty  
sure on all this speculation.
So if your app fits into the well defined sweetspot of what Rails  
does well, you will be able to publish your app and pay for resource  
usage like any other well managed utility instead of owning and  
managing your own server cluster.

But if you want an app that doesn't fit into the Rails sweet spot or  
if you need it today or if you need to mitigate lower operations  
costs than these new utility like hosting services might  
provide....well your back to square one ;-).

I spent about 2 months working with Rails this year.  I'm back to  
redoing the app in erlang.
