Traffic controlling for big websites :: Is anything special needed to be done
I was on facebook and simultaneously checking the Google+. A thing struck my mind. How do these websites handle such big traffic, do they have multiple version of their website running on different server ?? or they are hosted on one server which handles these things itself. I have developed few websites and hosted them on godaddy. But they didnt have parallel visitors as do facebook so i never came across such thing. Now i am working on a project which will deal with parallel request.

Take for example, the earlier days of facebook. What did the inventors of facebook do. Did they just made the website and hosted it on some server which handled traffic itself or they approached any other manner. 

Any light on this topic or any link will be helpful
