Cloud computing is an emerging computing model by which users can gain access to their applications from anywhere, through any connected device. A user-centric interface makes the cloud infrastructure supporting the applications transparent to users. The applications reside in massively scalable data centers where computational resources can be dynamically provisioned and shared to achieve significant economies of scale. Thanks to a strong service management platform, the management costs of adding more IT resources to the cloud can be significantly lower than those associated with alternate infrastructures.
