> Rackspace has nine data centers on four continents and more than 100,000 servers. For comparison, AWS also has nine data centers but on five continents and virtual machines in the millions. We believe AWS has more than 5x the IaaS capacity of the next 14 vendors combined. "Servers" and "virtual machines" are two different things. You could easily run 10 VMs on a single server at the lower end of the VM price range. So without more precise measurements, these numbers mean nothing. (What they say may still be true; you just can't tell from the numbers we're given here.)
