Clouds, as we know from our childhood, are tiny droplets of frozen crystals of water that are high in the sky hovering around our planet, Earth. What do these clouds do? They provide a service to the residents of planet Earth. They bring us rain. Something (clouds) that is somewhere (up in the sky) provides us with a service by bringing rain. This same concept of something somewhere can be applied to understanding cloud computing.
