The New York Times writes:
[Google] is stubbornly sticking to its do-it-yourself approach to technology. Even as it spends more than $1.5 billion this year on operations centers and technology, most of the hundreds of thousands of servers it will deploy are being custom-made based on Google’s own eccentric designs.
To be closer to its users and speed response time, it is building a worldwide string of data centers, including a huge site in The Dalles, Ore., with technologies it designed to reduce its ravenous need for electricity. These computers in turn use software developed with advanced tools that Google also designed itself. There are signs that Google is even preparing to create its own custom microchips.
