Cloud Computing Introduction
Working Description of Cloud Computing
Cloud computing: a model for enabling convenient, on
demand network access to a shared pool of configurable
computing resources (e.g., networks, servers, software,
applications, and services) that can be rapidly deployed
and/or released with minimal management effort or service
provider interaction.
Cloud Computing Introduction
