I've been a GCP customer for ~18 months and as recent as a year ago it still felt like very early days for sales and support. Well, actually it still feels like early days for support. The products, however, have been surprisingly good for the most part and seem more mature and well-engineered than their market share would suggest, especially in comparison to Azure.

So, I'm of the opinion that if they can figure out how to sell, they'll do quite well.
