I think it's a concern, but probably not as great as you might perceive. Centralization is fine (though maybe not great), as long as it is not forced. As long as the web remains open and free from a governance point of view, monopolies can only exist as far as one company can offer superior technology and offerings in general. If they fail (and thus that centralized node fails), as long as no one is 'forced' to stay with that centralized cloud provider, they can switch to competitors. Furthermore, in the future I can only see switching hosting providers becoming easier and easier to do, especially with services such as Docker becoming popular.
