It’s pretty simple, really. As more and more video hits the web, ISPs will find themselves crushed by demand that will drive up their backbone costs until all profit is driven from their businesses. Google will come to the rescue with regional data centers that will peer with local ISPs and relieve them of much of that burden, allowing the ISPs to actually cut back their backbone connections and run fewer servers, though at the cost of losing the big movie studio and TV network business deals those ISPs currently think will eventually make them rich. If we look at what Google will be offering, it is bandwidth and server power. So to compete with Google will require bandwidth and server power.
