So, so create the list of top #Cloud players we did our own quick&dirty study. We wrote down keywords: 
– cloud computing solution
– cloud computing provider
– Iaas, saas, paas
– comparing cloud computing solutions 
– comparing cloud computing providers.
Then we googled those, wrote down the hits, did a bit of validation and that was it.
Do you know of any more robust rankings in the Cloud? I’d appreciate your view on this.
