Data centers have some special properties. The servers have to be online 24/7 at 365 days per year. Consequently, the data center operator has to make sure that the power supply is never disconnected. Therefore, data centers have always additional diesel generators for the case of a blackout. Furthermore, data centers have extensive cooling, that also is responsible for half of the electricity consumption.
Where are the hotspots?
When launching a cloud server at one of the American market leaders, you will directly the most important cities for data centers in Europe: Frankfurt, London, Amsterdam and Paris. These cities host an extraordinarily high number of data centers and are well-connected by cables with American data centers. There is also an increasing amount of data centers in Scandinavia. This especially makes sense because of lower temperatures that reduce cooling power costs.
