Cloud computing provides users with access to a shared collection of computing resources: networks for transfer, servers for storage, and applications or services for completing tasks.
The compelling features of a cloud are:
On-demand self-service: Users can automatically provision needed computing capabilities, such as server time and network storage, without requiring human interaction with each service provider.
Network access: Any computing capabilities are available over the network. Many different devices are allowed access through standardized mechanisms.
Resource pooling: Multiple users can access clouds that serve other consumers according to demand.
Elasticity: Provisioning is rapid and scales out or is based on need.
Metered or measured service: Cloud systems can optimize and control resource use at the level that is appropriate for the service. Services include storage, processing, bandwidth, and active user accounts. Monitoring and reporting of resource usage provides transparency for both the provider and consumer of the utilized service.
