Why Cloud Computing?
Definition of 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, applications,
and services) that can be rapidly
provisioned
and
released
with
minimal
management
effort
or
service provider interaction.”

Why Cloud Computing
Benefits of Cloud Computing
Reduced Cost
Cloud technology is paid incrementally,
saving organizations money.
Increased Storage
Organizations can store more data than
on private computer systems.
Highly Automated
No longer do IT personnel need to worry
about keeping software up to date.

Why Cloud Computing
Benefits of Cloud Computing
Flexibility
Cloud computing offers much more flexibility
than past computing methods.
More Mobility
Employees can access information wherever
they are, rather than having to remain at their
desks.
Allows IT to Shift Focus
No longer having to worry about constant
server updates and other computing issues,
government organizations will be free to
concentrate on innovation.

Emerging Cloud
Moving to the media cloud
A shift to the edge
the shift of intelligence away from the network core and
toward the network edge
a similar movement of storage and some functionality
away from the home and toward the network edge.
