I just came across a very interesting article on The Economist which describes the trend about creating new data centers around the world. Basically corporations are investing more money than ever into those super computing warehouses, and the challenge now is to find locations that will supply enough and reliable energy to them. Here is a quote:
Internet firms, meanwhile, need ever larger amounts of computing power. Google is said to operate a global network of about three dozen data centres with, according to some estimates, more than 1m servers. To catch up, Microsoft is investing billions of dollars and adding up to 20,000 servers a month.
As servers become more numerous, powerful and densely packed, more energy is needed to keep the data centres at room temperature. Often just as much power is needed for cooling as for computing. The largest data centres now rival aluminium smelters in the energy they consume. Microsoft’s $500m new facility near Chicago, for instance, will need three electrical substations with a total capacity of 198 megawatts. As a result, finding a site for a large data centre is now, above all, about securing a cheap and reliable source of power, says Rich Miller of Data Center Knowledge, a website that chronicles the boom in data-centre construction.
I wonder if in the near future we will see a trend towards the outsourcing of data centers.
