In Carrier Cloud, the on-demand edification of a carrier-grade mobile network on the cloud in an elastic way provides a flexible network thanks to the Network Functions Virtualization (NFV). It allows using cloud computing infrastructure, instead of having custom hardware appliances for each network function, and setting up a mobile, flexible, dynamic, and rapidly deployable network. These features provide to the network the programmability and flexibility that makes it able to dynamically adapt to changing user's mobility and demand.
