What is it?
“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, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”
-- Mell & Grance, 2009
What is it?
“[Cloud computing is] the delivery of scalable IT resources over the Internet, as opposed to hosting and operating those resources locally, such as on a college or university network.”
-- EDUCAUSE, 2009

with few to no intermediaries Providers distribute resources dynamically
