In the case of AWS, I can see the advantage, you're renting a resource you need, rather than buying it. I guess I just don't see how you extract similar amounts of revenue from Docker...
Redhat is valued at ~1.3B USD. Github, currently at ~2B USD. How do you justify 10B USD for Docker. Obviously you can (they did), I just don't understand how this is done well. Does anyone have a better insight here?
