In general, I would say marketing is the thing Google does the best, which is why I find it surprising they are unable to market these products.
Their entire business proposition revolves around getting products and services in front of exactly the people looking to spend money on those things. They were able to market Chrome super effectively, taking a lot of share from IE. Chromebooks and their flagship phones get lots of attention.
So why can't they get the message of GCP in front of the most likely customers?
I think there's a consumer vs. enterprise gap there. Chrome, Android, Chromebook, Docs/Drive (originally), etc. are all consumer products and gained traction in that space. Marketing to enterprises for something like GCP is quite a bit different and requires a different strategy that Google just hasn't really mastered yet.
