I'm always surprised when people suddenly realise a cloud is just a data centre. Zettagrid switched off their UPS and took out the 'cloud' in Australia the other night. I got about 100 support calls (after the support helpdesk came back - it was hosted in the 'cloud') where I had to explain that a cloud is just a bunch of VMs... sitting on physical hardware.
