Ben Reid: Head in the Cloud

Views of the Cloud (2): A topology of submarine cables

Published 15 April 2008, 09:42 PM

Physically, the Cloud is made up of the massive datacenters which provide processing capacity, together with all of the network connections in the world which provide the bandwidth to make it all work. Take a look at this map from the UK Guardian which illustrates how all the submarine cables in the world are arranged. According to this diagram, the world's total cable capacity is a staggering 7.1tbps (terabits per second) - and growing. Compare that image with the images of the logical topology of the internet at http://www.caida.org/research/topology/as_core_network/2007/images/ascore-simple.2007_big.png and http://mundi.net/maps/maps_020/ - these are fascinating visualizations of the (early) infrastructure of the Cloud.
