Personally I'd go for C#, but it also depends on the cloud platform you want to use. For example, see a demo on how to start with Windows Azure here: http://msdn.microsoft.com/en-us/azure/dd327648.aspx
I recently read that PHP will also be supported on a specific cloud platform, but can't remember which one.
And yes, clouds are definitely used in the market, especially in heavy duty calculations (weather forecast, biology).
