You heard of phrase 'Pie in the Sky', how about some Pi in the Cloud?
Researchers from the University of Glasgow have linked 56 Raspberry Pi computers sitting in racks made from Lego to create a mini cloud computing platform modelled on those run by Amazon, Google and Microsoft.
The platform is designed to give students an insight into the architecture of today's major cloud platforms – whose inner workings are often hidden from view.
"For an initial investment of less than £4,000, we've been able to build a Linux-based system which allows researchers and students complete access to a working cloud computing infrastructure at a tiny fraction of the cost of its commercial equivalent," said Dr Jeremy Singer, of the university's School of Computer Science.
The Raspberry Pi is a $35 credit-card sized Linux computer designed to be affordable to kids, in a bid to inspire them to learn to code. Since the Pi's launch last year more than 1.2m boards have been sold.
