What a misleading conclusion
"rule the cloud"? Is everyone high?
No, the IDC research specifically looks at hardware sales to on premise for the 2nd tier cloud providers (e.g. rackspace, CDC, these guys). This isn't cloud, it's not even nearly cloud. It's pretty much channel with a twist.
Meanwhile, AWS ALONE did $7.88bn last year - nearly as much as your entire table combined.
