Quentin Hardy at The New York Times:
SAN FRANCISCO — Imagine building an enormous beach resort, maybe the best in the world. Instead of renting the rooms, you charge guests based on the grains of sand they touch. You charge very little per grain, but if they lie on enough of them, it adds up.
That is one way to think about what is going on at the world’s biggest cloud-computing companies.
Good article. Good metaphor.
