Hell, I bet there are insiders who were surprised about the decision to close up shop on Google Inbox. There's no guarantee that Cloud and Domains will never be closed, but that's on the level of RIM no longer making Blackberries. Google's a modern Internet company and has bet, and bet big, on being a leading cloud services provider, and Domains are a key component to having a vertically integrated offering.

Google is a public company and as such they are required to release certain information in annual report, so their investment in the cloud is verifiable.
