Heck I worked at Amazon and even then I couldn't tell you the total datacenter space, they don't even share it internally.
But I wonder how much of their infrastructure is publicly mappable, compared to just the part of it that's exposed to the edge. (Can you map some internal instances in a VPC?)
That said, I'm sure there are a lot of side channels in the provisioning APIs, certificate logs, and other metadata that could paint a decently accurate picture of cloud sizes. It might not cover everything but it'd be good enough to track and measure a gradual expansion of capacity.
Last I updated my spreadsheet in 2019, Google had $17bn in investments across their datacenters, totaling 13,260,000 sq ft of datacenter space. Additional buildings have been built since then, but not to the scale of an additional 30mil sq ft.
Amazon operates ~80 datacenter buildings in Northern Virginia, each ~200,000 sq ft -- about 16,000,000sq ft total in that region, the other regions are much much smaller, perhaps another 4 mil sq ft. When I'm bored I'll go update all my maps and spreadsheets.
As for the dollars, were they just in 2019 or cumulative? The Google ones seem low compared to numbers from earnings.
Amazon builds out 32MW shells, and the most utilized as of 5 or 6 years ago was 24MW or so, with most being much less than that.
I am surprised we havent heard about private electrical grid built out by such companies.
Surely they all have some owned power generation, but then if they do, the local areas where they DO build out power plants - they should have to build capacity for the local area, mayhaps in exchange for the normal tax subsidies they seek for all these large capital projects.
Cant wait until we pods/clusters in orbit. With radioisotope batteries to power them along with the panels. (I wonder how close to a node a RI battery can be? Can each node have its own RI?) (sas they can produce upto "several KW" -- but I cant find a reliable source for max wattage of an RI...)
SpaceX should build an ISS module thats an AI DC cluster.
And have all the ISS technologies build its LLM there based on all the data they create?
I'll finish my other maps and share them later...
Facebook publishes this data.
