Safer in the Clouds
In the old times, people used to exploit the bakery's oven for their home-made bread. Similarly, people utilised the public mill to obtain flour from their wheat. In both cases, people did not own the physical infrastructure to process their products, neither had they invested on it. Instead, they rented usage from a third-party provider. Under this regard, the idea of cloud computing is not completely new, it just updates the above model and adapt it to the Internet world. Cloud Computing customers do not invest on hardware, software or services, but they just pay providers to use them, either on a utility or a subscription basis. They rely on clouds for infrastructures, platforms, and software.
