Not sure whether we should replace "Big" with "Scary" or replace "Data" with "Brother".
The 'bigness' is not the data center. The bigness is found in its reach.
I had a client that developed an automated web-based business system written in C++ back before most had though to do something like that. It was an automated customer survey system. It cost them about $45K to develop it. It ran on a small "server" (more like a glorified P5 desktop) they built for about $3k. Today you could build one twenty time more powerful for about half that. (Although the programming would probably now run in the six digit range if you were doing it today.)
That little bugger generated at least $20K worth of revenue for them every 24 hours. Still does actually. Just think: a multi-million dollar business running off a homebrew computer. Awesome!
Like burlesque queen Gypsy Rose Lee so famously said: It isn't how much you got. It's how you use it that counts.
