How to operate a server on the Internet? From the beginning, the usual way has been to buy a computer and put it in an expensive data center where you rent space.
Now, people set up a bunch of computers in the data center and they rent you time on them. It's a cheaper way to do it in a lot of cases; you own less of the infrastructure, but do you really need to? When we were doing a ton of traffic (when IotD was big and Facebook was small), we needed that, but now we don't. So we'll save money, save a little effort and apparently get a server that's avg 5ms faster to the net as well.
5 milliseconds here, 5 milliseconds there, it adds up
not really
