4. a revolution

5. it will change

6. how we
manage IT

7. New Dawn
• Is Cloud Computing fundamentally different from what came
before?
• Larry Ellison, CEO of Oracle, in a 2009 interview
– “All the Cloud is, is computers in a network… Our industry is
so bizarre. I mean, they just change a term and they think
they’ve invented technology.”
• Marc Beniof, CEO of Salesforce.com, at the Oracle OpenWorld
2010 conference
– “Our definition of Cloud Computing is multi-tenant, it’s faster,
half the cost, pay as you go, it grows as you grow or shrinks as
you shrink. It is extremely efficient. We’re not going to show
you computers taller than you. We’re not going to show you a
cloud in a box because clouds don’t come in a box. They never
have. That’s the whole idea”

9. From water-wheel to Utility power
• To understand the revolutionary qualities of Cloud
Computing, it is appropriate to utilize a well-worn, but
accurate analogy that compares Cloud Computing to a
traditional utility service like water or electricity.

10. From mainframes to Cloud
• At one time corporations built out high-performance
proprietary networks to link… different locations… As the
Internet became the default connection between
universities, government agencies and some companies, the
cost of not having an [Internet protocol] network internally
went up and up.

11. The benefits of the Cloud
• Virtualization – The ability to increase computing
efficiency
• Democratization of Computing – Bringing enterprise
scale infrastructure to small and medium businesses
• Scalability and fast provisioning – Bringing web scale
IT at a rapid pace
• Commoditization of infrastructure – Enabling IT to
focus on the strategic aspects of its role

12. Virtualization
• The ability to increase computing efficiency

13. Democratization of Computing
• Bringing enterprise scale infrastructure to small and
medium businesses

14. Scalability and fast provisioning
• Building and adding resources at a rapid pace

15. Commoditization of infrastructure

16. Strategic role of IT
• IT tasks in the cloud domain will include:
– Guiding the company's cloud strategy
– Evaluating provider offerings
– Negotiating contracts and service
– Determining which applications or data are safe or
appropriate for the cloud
– Collaborating with the company's procurement and legal
departments
