Yes but it's tiny compared to Google Revenue and when I messed with it, it wasn't 100% certified for Government use. Meaning if you used it for Government, you could only use select products vs Microsoft and Amazon which certified almost all their products.
It was 10B out of 84B in the latest quarter and growing a lot faster than other revenues. It's not really what I would call tiny.
GCP doesn't make money
Neither does azure if you remove AD\exchange from it.
