So interestingly, they made that bet internally, standardised their own platform and then released some sort of abstracted on demand cloud compute services. However the tools they developed for themselves and the SOA style of development would have been valuable to others too. Google did the same. Netflix did the same. None of this stuff really emerged as a product. I'd argue it still hasn't. IF it had, maybe we'd be doing things a bit differently now. But then I guess proprietary RPC based architectures sort of failed along the way when we look at the list you mentioned.

The didn't fail per se, hence why we now have gRPC, after WebServices, Jini, RMI, .NET Remoting, XML-RPC, JSON-RPC,...

Every generation keeps re-inventing them.
