This generalising misses the point for me. If you're trying to scale, fast, into the global stage "half a rack of colo" isn't going to cut it. You're going to need presence everywhere and that can be impossible to deploy fast. If you're targeting say a single market, say North America, with fewer larger clients you're likely to be able to manage it from two DCs and can realistically manage it yourself. It's just "right solution for the right situation". Cloud is absolutely not always the right solution.
