3. What is it?
“It’s a wireless connection to stored
data and information which is very
easily retrievable and as a
consequence enlightens people
like you and I who don’t
understand what it means”

4. What is it?
• Cloud computing enables customers
to access IT services from the cloud
with minimal infrastructure,
investment or services deployed in-
house. Internet
• Roughly, it describes highly scalable
computing resources provided as an
external service via the internet on a
pay-as-you-go basis

5. What is it?
• Economically, the main appeal of
cloud computing is that customers
only use what they need, and only
pay for what they actually use.
Resources are available to be Internet
accessed from the cloud at any
time, and from any location via the
internet.

6. What is it?
• Parallels to this concept can be
drawn with services such as the
electricity grid. You pay for what
you use and the supplier provides
the architecture. Internet

7. Why now ?
