It could take a while yet before all companies big and small start using the cloud to its full potential though ... in my experience people in management are usually against it, citing data security issues.
You'd be surprised. I've contracted for the some 3 letter federal agencies and they're alright with certain material being hosted in the cloud. (1) We didn't use AWS but they were fine with standard RSA keys. MS/IBM realizes the discomfort management has though, and addresses it with "partial virtualization" solutions.
Part of it is being outside the US as well- there is a reluctance to keep sensitive data on servers owned by a foreign company. Attitudes are changing though ... MS and Amazon for example have a really good presence in Australia these days.
