Cloud computing is a term that refers to sources and computer systems available on demand through the network, which can provide a number of computer services integrated without being restricted local resources in order to make it easier for the user and include those resources space for data backup and synchronization self also includes processing capabilities software and scheduling of tasks and push e-mail and remote printing, and the user can control when it is connected to the network in these resources through a simple software interface simplifies and ignores a lot of detail and internal processes.
Cloud computing has become increasingly popular because it offers users the illusion of having infinite computing resources, of which they can use as much as they need, without having to worry about how those resources are provided. It also provides greater scalability, availability, and reliability than users could achieve with their own resource
The core property in cloud computing that held computing "in the cloud"; for clarity, the treatment process (and related data) is not confined to the place (places) private and unknown. Thus, this model is the antithesis of the treatment process is located in one or more of the servers are well known.
Exposure model cloud of criticism and attack because of privacy advocates, for the ease of large governing the hosting companies for services cloud, and then, can impose censorship and domination, whether legal or illegal, the communication process as well as the data stored in between the user and the host company
Introduction
Cloud computing has become a ubiquitous term and largely discussed topic in the global information technology (IT) world. Cloud computing has changed dramatically the ways in which organizations and individuals communicate, collaborate and compute. The concept of cloud computing ensures a cost–effective transformation of utility computing principle that allows users and providers
