The question was asked to CIO's to "name their preferred public cloud provider". It's not clear to me what preferred means here. I'd bet a large number of them still have a large amount of on-premise. Does preferred mean the vendor with the highest compute workload, or the one they would pick if they were to move to the cloud? I have to think that it would be the latter, because moving that much compute workload off of Google's Cloud between 2014 and 2015 would be a big effort.
