just thought id post and say i am currently a huge fan of cloud computing.
Been using various offerings (amazon e2 / flexiscale etc) for a while and just swapped to a webhost running on cloud computing as well as started to use huddle (running on cloud computing) its a brave new world.
I was given a task the other day to setup 2 servers (1 pbx 1 office comms server 2007) within an hour i was up and running on both systems and had spent around 40p :)
Normally i dont have much luck with virtual machines as i find they get very upset about networking and ports but so far nothing bad to report.
More info from experts.
