Public and Private Clouds for the UK HE Sector

Why does the UK HE sector need to build its own Cloud infrastructure when we can simply be consumers of an existing Cloud services provided by Amazon and similar providers?  Especially, as suggested by the final speaker at yesterday’s Virtualisation and the Cloud Eduserv symposium, especially as large prestigious US HE institutions such as UC Berkeley are making effective use of Amazon services and have gained a better understanding of the hidden costs and challenges of running one’s own Cloud service.

The answer needs to be more than “Data protection legislation means we can’t use US Cliuyd services”.
