As news outlets create headlines such as "A Cloud & A Prayer," "The Cloud Is the Computer," and "Leveraging Clouds to Make You More Efficient," many readers have been left with cloud confusion. Many definitions exist for cloud computing, and a uniform definition is hard to find. In its most basic form, cloud computing is the availability of IT-type needs offered as services, often through a third-party vendor. Adding to the confusion are conflicting ideas on what constitutes the various areas of cloud computing.

The author also discusses how cloud computing vendors, such as Google and Amazon, are constantly working to improve and add to their cloud services.
