I have always given credit to Microsoft Visio as the reason the term “cloud computing” came to represent services provided outside the data center. Whenever the network geeks want to draw out the details of their networks, they invariably use Microsoft Visio to create the pretty pictures using the pre-canned cloud graphics within Visio to depict the connections between locations.
Therefore, when talking about equipment outside the data center, they would always say “it’s in the cloud”. They used the cloud metaphor to simplify the drawing of all the complex hardware and software components that made up the wide area network connections, or even their internal network connections in the data center. They hid the all the complexity by using a level of abstraction (the picture of a cloud) to represent the complex stuff within it. The metaphor stuck

Storage virtualization does the same thing for data. Storage virtualization creates the abstraction layer between the applications running on the servers, and the storage they use to store the data.
