Mais um caso: Escalando Ruby

*

In a short three months Friends for Sale (think Hot-or-Not with a market economy) grew to become a top 10 Facebook application handling 200 gorgeous requests per second and a stunning 300 million page views a month. They did all this using Ruby on Rails, two part time developers, a cluster of a dozen machines, and a fairly standard architecture. How did Friends for Sale scale to sell all those beautiful people? And how much do you think your friends are worth on the open market?
