For Azure, all of it. Microsoft clumps Azure together with their server software (e.g. Windows Server, SQL Server) licensing when reporting the revenue, but give more fine-grained information on growth rates. This is the latter. (We also know the Azure business was already massive at $34 billion in 2022, since it got revealed during one of Microsoft's ongoing antitrust cases.)
For Google, I'm not aware of a reliable way of estimating the GCP vs. Workspace numbers. But they get asked it during earnings calls, and the answer has always been that the GCP growth is substantially faster than the Workspace growth.
