You can't go a month without hearing about some price drop by a major cloud computing provider, with others quickly following suit. Though it seems like a race to the bottom, in fact the cloud providers are starting to make real money.

Public clouds function much like utilities. How much businesses pay for these utilities depends directly on how they consume cloud-based resources such as storage, compute, and applications. Companies that consume cloud services efficiently pay less, and the inefficient ones pay more.
