Cloud Computing is

a revolution

it will change

how we manage IT

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”

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.

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.

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

Virtualization

• The ability to increase computing efficiency

Democratization of Computing

• Bringing enterprise scale infrastructure to small and medium businesses

Scalability and fast provisioning

• Building and adding resources at a rapid pace

Commoditization of infrastructure

SAN Storage

$2 - $10/Gigabyte

$1M gets:0.5Petabytes

200,000 IOPS1Gbyte/sec

NAS Filers

$1 - $5/Gigabyte

$1M gets:1 Petabyte

400,000 IOPS2Gbyte/sec

Local Storage

$0.05/Gigabyte

$1M gets:20 Petabytes

10,000,000 IOPS800 Gbytes/sec

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
