If it's not ad sales or search - I don't trust Google enough to base long term projects on it. _Maybe_ add gmail to that, perhaps. Possibly Suite (since at least they charge for it). For me at least, Google Cloud is still not quite emerged from "interesting, but not sure it'll be around long term yet" status. I'll use it as part of a multicloud architecture, or for prototypes/short-term projects. But I haven't yet been able to convince myself to recommend jumping both feet into a GoogleCloud-specific project architecture - in the same way I happily recommend/design/deploy AWS-specific projects all the time.
