I have always wondered why Google didn't buy Sun? They propbably were at the time (and probably still are?) the biggest corporate users of both Java and JavaScript (which, of course, don't share anything beyond the name).
I bet AWS would give them a good run for their money on that metric. I got the impression that Google was predominately a C++ shop, whereas the rumor mills tell me that most of the AWS control plane is in Java (I am pretty sure I've actually gotten a stack trace from an AWS API once or twice, but foolishly I didn't save it)
The world would be a much better place if Google had googled Java twenty years ago.
