What is Cloud Computing???

Def:

Cloud computing is a model for enabling ubiquitous, convenient, ondemand

network access to a shared pool of configurable computing resources

(e.g., networks, servers, storage, applications, and services) that can be rapidly

provisioned and released with minimal management effort or service provider

interaction. (by NIST)

“an Internet based computing paradigm that delivers on-demand software and hardware

computing capability as a ‘service’ through virtualization where the end user is completely abstracted

from the computing resources”
