That's huge growth for already enormous businesses. I spend a lot of time thinking about how startups can effectively compete against these businesses – which are often bankrolled by best-in-class consumer businesses and enjoy economies of scale.

But as these clouds start to look at higher-margin services that they can deliver at a lower cost and with better distribution, it's becoming tougher and tougher.
