Google Apps is not GCS. If you wanted to compare that number you'd have to throw in Office 365/Azure into the same number and it would dwarf Google.
Google has ~3% market share compared to Microsoft's ~28% and Amazon's ~40%. Not even in the same league at the moment. Google is more on par with IBM and Rackspace, for now. Google will undoubtedly make strides in the space, but they haven't been tested.

Where does this number come from?
If it is based on the revenue reported, be very careful with Microsoft's numbers. They report a lot of products as "Azure intelligent cloud", including Office suite subscriptions, on-premise server licences, and software (Windows, SQL Server) licensing revenue from other cloud providers in that number.
Pretty soon their claimed growth is going to flatten out, because they couldn't find any more revenue to report as "Azure intelligent cloud", like PC hardware ...
People have been throwing this conspiracy theory around for years...even though you can look at Microsoft's earnings reports and see they are broken out as different line items.
