If Twitter is a for-profit venture, I'd be very surprised if usable
details about how they plan and manage load, scalability and capacity
are available without an NDA. This is something we performance engineers
consider "The Family Jewels", although perhaps curious folk in other
disciplines wonder what the fuss is all about. :)

And yes, Google *does* throw a ton of compute gear (and Map-Reduce) at
their searching and indexing, which, as far as I know, is *not* written
in Ruby and does not involve Rails.

And just on the off chance *you* would like to become a capacity
planner, there's to my knowledge only one place outside of a university
where you can learn how:
