Actually for twitter it could very well be the cheapest option At an industry event last fall, I suggested this very strategy to the newish VP of ops/engineering/scaling Twitter had just hired from the porn industry. My advice was Professor Frink-ish: "why not just buy one really big computer?" I was only half joking, but he wasn't impressed by my idea. Perhaps he remembered my name and that's why their recruiter has not called me back.
