Sitting in just four small lego racks the Pi cloud may be one of the few cloud platforms that you can carry under your arm.
"One of the great things about the Pi cloud is that it's portable. We can literally pick a chunk of it up and take it directly into lectures to do live demos," said Dr David White, of the University's School of Computing Science, adding the platform is used to teach about software deployment and networking.
"To do something like this using x86 nodes would be much more expensive but we would also be restricted to putting it in a machine room and at that point you've lost the hands-on teaching aspect and the portability.
"The main purpose is to build something that is logically similar and not computationally similar. Obviously pound for pound and watt for watt you'd be much better off building an x86 cluster if you wanted to do computation."
