Cloud Computing

A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., servers, storage, networks, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

• shared pool of computing resources

• rapidly provisioned

• minimal management effort

* differentiates from just data center/virtualization/shared storage
