In reality, however, cloud computing is very much tethered to the physical world, through football-field-sized warehouses of connected servers that enable it. A computing job, though it can be accessed from anywhere in the world, can't be easily moved from one warehouse to another. It can't even necessarily be moved from one area of a warehouse to another area of the same warehouse. This is a problem for two reasons. The first is that it's inefficient and drives the price of cloud-based applications that use data centers upward.
