    2. 2. Cloud computing is a model for enablingubiquitous, convenient, on-demand networkaccess to a shared pool of configurablecomputing resources (e.g., networks, servers,storage, applications, and services) thatcan be rapidly provisioned and released withminimal management effort or serviceprovider interaction. This cloud model iscomposed of five essential characteristics,three service models, and four deploymentmodels.
