“What would you do if you had 1,000 times more data?” asked Google Senior Software engineer Christophe Bisciglia some time ago. To me this seems to be THE big point with cloud computing. After learning about economical and market forces driving the cloud wave, I still think that money and flexibility alone are only half the truth. Even if those two arguments are important for most private and corporate IT users, there are a number of drawbacks like security issues or the question of who is in control of the data.
My guess is, that clouds will have their final breakthrough when we’ll have more applications that exploit the new possibilities the cloud computing paradigm offers. More stuff like Google and Amazon. Or even smaller but innovative like Gigaspaces.
