Hello,
I don't really means what cloud computing really means. I have this article: Cloud Computing
"he phrase is often used in reference to network-based services, which appear to be provided by real server hardware, and are in fact served up by virtual hardware, simulated by software running on one or more real machines. Such virtual servers do not physically exist and can therefore be moved around and scaled up or down on the fly without affecting the end user, somewhat like a cloud."
Such Virtual Server do not physically exist - Is that means that the Virtual Server does not physically exist for Buyers only but still exist for the Sellers ?
What I mean by that is the Sellers still have to set up a data center which consist of multiple server computers (which physically exist) whereas the Buyers only renting those server spaces through a distance (Internet/ Network).
Is that what it means ?
