Innovation ousts orthodoxy. Soft-switch has replaced telephone exchange equipment. Undersea optical fiber cables have marginalized satellites in intercontinental and transcontinental connectivity. Terrestrial optical fiber networks – along the highways, railway tracks, power grids and gas pipelines – are replacing microwave radio links. All these physical networks lead to data centers at home and abroad.
My favorite definition of Internet is from Jim Cowie: “The Internet is a robust virtual infrastructure comprised of tens of thousands of communicating enterprises, each seeking to maximize profit according to local rules and business conditions.” And the Data Centers function as the factories-cum-warehouses of Internet. Thousands of servers and routers being stacked across the vast space emit enormous heat in the air. That’s why highly sophisticated air cooling systems are installed to maintain proper temperature and Internet. Any glitch in the power supply system results disastrous consequences.
