A cloud is a network or internet that is situated in a remote location and offers services on public networks or on private networks (such as wide area networks, local area network or virtual private network). These services include online data storage, infrastructure and application. Cloud computing refers to a set of information technology services that are offered to a customer over a network on a leased basis. They are normally delivered by a third party provider who possesses the infrastructure.
