These questions can't really be answered, and the numbers are fuzzy.
Cloud, Server and DC licences are in tiers. It is possible to add up the various levels of tier that are licenced (e.g. 1,000,000 10 user tier licenced systems can be counted as 10 million users, and 1,000 250 user tiers are 250,000 and so on). But
So you might get some numbers, but you'll need to bear in mind that they're not going to be accurate.
