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.”

millions of users will dramatically change the nature and

cost of solutions deliverable to enterprise..”
