In both cases Google regarded the technology as a competitive advantage in the business they were in (web search), so naturally wanted to keep it internal. Maybe almost as important, they were so far ahead on those technologies that making a viable product out of them would have been a huge effort with no benefit to search. Google tech has always been an "island". Even when they did release GCP, the offerings like AppEngine and transparent networking were incomprehensible to customers who just wanted to lift-and-shift their existing datacenter, not adopt Google practices. Amazon, on the other hand, has no qualms about converting their internal expertise into products ("turn every major cost into a source of revenue" [0]) and giving customers what they ask for.
