Cloud Computing
What is Cloud Computing?
Cloud Computing
defined as “Clouds are
hardware-based services
offering compute,
network and storage
capacity where:
Hardware management is
highly abstracted from
the buyer, Buyers incur
infrastructure costs as
variable OPEX, and
Infrastructure capacity is
highly elastic” -

Report: “Clearing the
Air on Cloud
Computing
Cloud Computing defined
as “a pay-per-use model for
enabling available,
convenient, on-demand
network access to a shared
pool of configurable
computing resources (e.g.,
networks, servers, storage,
applications, services) that
can be rapidly provisioned
and released with minimal
management effort or service
provider interaction.” -
National Institute of
Standards and Technology
(NIST)$
Cloud Computing defined as
“Clouds are a large pool of easily
usable and accessible virtualized
resources (such as hardware,
development platforms and/or
services). These resources can be
dynamically re-configured to adjust to
a variable load (scale), allow-ing also
for an optimum resource utilization.
This pool of resources is typically
exploited by a pay-per-use model in
which guarantees are offered by the
Infrastructure Provider by means of
customized SLAs.” - Paper by
Vaquero et. al.: “A break in the
clouds: towards a cloud
definition”
