Of course, YouTube is just one of the forces behind the rapid proliferation of these huge data centres. "Microsoft figures it will expand its network of them 64-fold over the next few years, just to handle some 200 services, including X-box online gaming, video and corporate software rented over the web. But YouTube apparently adds about 57,000 video clips a week to its library, and "Cisco's own WebEx service, designed for videoconferencing in the office, hosts up to 7 million minutes a month." Cisco CEO John Chambers uses their system to reduce his travel days, and the company is working on delivering him to customer offices by hologram. "Video" Chambers says "is the only technology I've seen CEOs turn around and sell to other CEOs."
Will you be able to recognize a data centre should it settle in your neighbourhood? Hint: look for windows with frost on the INSIDE. Most of that electricity is running the air conditioners.
For more on video from John Chambers please see my post of August 30. Suitably, Mr. Chambers delivers his thoughts by video.
