So What is Cloud Computing?

“Cloud computing is a model for

enabling convenient, on-demand

network access to a shared pool of

configurable computing resources

(e.g., networks, servers, storage, ap

plications, and services) that can be

rapidly provisioned and released

with minimal management effort or

service provider interaction.”
