Cloud Computing?
Copyright © 2011 LOGTEL

10. Definition
 Wikipedia - a style of computing in which dynamically
scalable and often virtualized resources are provided as
a service over the Internet. Users need not have
knowledge of, expertise in, or control over the
technology infrastructure in the "cloud" that supports
them.
 Academic (simple) - provide on-demand resources or
services over a network, often the Internet, with the
scale and reliability of a data center.
 Mine – distributed mainframe, reachable form any
device connected to the internet

11. Oracle definition ;-)
“...we’ve redefined Cloud Computing to
include everything that we already do...
I don’t understand what we would do
differently ... other than change the
wording of some of our ads.”
 Larry Ellison, CEO, Oracle (Wall Street Journal, Sept. 26, 2008)
