Google DCs: 'Impossible to Duplicate?'

Google is much more capital-intensive than our competitors and we're much further along in the buildout of data centers. We have a competitive advantage because we have the cheapest and most scalable architecture. We hope that in the course of innovation, we will be able to build products that are almost impossible for our competitors to duplicate, simply because we've learned how to implement them at scale. The Internet is a scale business, and running large Internet scale businesses is very, very difficult. Virtually all of our capital expenditures go into the data center.
