Since when is AWS not a juggernaut...
So, yeah, AWS is awesome. But its not like others can't/aren't catching up.
Tomorrow AWS is a $10 billion sales business, with offerings that are 10 times more powerful at 1/3rd the cost that they are now. And that is what Bezos has his eye on.
You're not Reddit? The value proposition will continue to skyrocket for smaller entities too, and it will swamp most of the market. That is the Amazon model, and they're clearly going to stick to it. At scale (AWS is probably only 5% to 10% the scale it'll be in just five years), very few will stand a chance at keeping up.
And slowly eating up AWS? No. That's Digital Ocean eating the lower end of the market. Rackspace outsources their CDN to Akamai, and their Cloud experience is damn near abysmal.
While a lot of technology leaders might admire Bezos for his leadership of Amazon, I wonder how many fear him. Most of what Amazon does, does not compete with technology companies. In the few places they do, they're not a juggernaut.
For example, despite years of effort, the Kindle Fire has not significantly harmed the market share or margin of the iPad. Google and Samsung have done far more damage to Apple. And Amazon's media sales are not much of a threat to Apple: they haven't stolen significant share, and Apple does not try to make money on content anyway.
I think there are a lot of people who do fear Bezos, but they are mostly retailers and hosting companies.
