Cloud computing technology model Cloud computing, a technology model in which data and information processing takes place entirely on the Internet, is becoming a recent major trend. There are many advantages of this model for users such as: no cost of maintaining infrastructure, constantly updating maintenance, accessible anytime, anywhere, on any device … Even tech giants like Microsoft are aware of this trend and make cloud versions for their Microsoft Office pet.
