“Cloud Computing” means different things to

different people, and that’s OK.

Fact #1


Computing in which applications, data and

IT resources are provided to end users as

services delivered over a network.


Cloud Computing Definition


Types of Clouds



Public Clouds

-

Allows access to technology
-
enabled services
without knowledge of, expertise
with, or control over the technology

infrastructure that supports them.

-

Also called “external cloud.”



Private Clouds

-

Activities and functions are provided “as a service,”
over a company’s intranet
.

-

Built by an organization for its own users, and everything is delivered within the
organization’s firewall (instead of the Internet).

-

Organization
has knowledge

of the infrastructure and possibly some control.

-

The private cloud owner does not share resources with any other companies.


-

Also called an “internal cloud.”


Hybrid Clouds

-

External and internal service delivery methods are
integrated
.

-

Rules and policies are established by the organization based on factors such as
security needs, criticality and underlying architecture.

-

Activities and tasks are allocated to external or internal clouds as appropriate.



Cloud Computing Models


Co
-

Location

Dedicated data center facility designed with resources which includes a
secured suite, cage or cabinet, regulated power, dedicated Internet
connection, security and basic support.


Infrastructure as a Service (IaaS)

Raw computing power. Includes servers, networks, storage,
management, and reporting.



Platform as a Service (PaaS)

Consists of the IaaS layer along with an Operating System and other
building blocks. A hosted server running OS/400 is an example.


Software as a Service (SaaS)

Applications configured for each customer that run as a hosted service.

Cloud Computing is overhyped right

now but it is definitely a shift in the

way we deliver computing.

Fact #2


Industry Shift


“Computing is undergoing a seismic shift.”
-

Microsoft Nov 2010


“We expect cloud computing to account for $7 billion of our net
revenue by 2015.”
-

IBM 2011


“The money spent on cloud computing is growing at over five
times the rate of traditional, on
-
premise IT.”
-

Cloud Connect
2010


“Dell is investing $1 billion to expand cloud computing.”


April
2011


“2011 is Year of Platform as a Service (PaaS), and it will engulf the
software industry.”


Gartner 2011


“Cloud computing is changing the way that IT resources are
utilized and consumed.”


Cisco



Foundation



Client


Server



Virtualization



Automated provisioning of IT resources



Improved Networks



Software Multi
-
tenancy: a single instance of software
runs on a server, serving multiple clients


Cloud Computing is not

a “one size fits all” solution.


Fact #3


Public, Private and Hybrid Clouds Adoption


Early Adopters





Need for a secondary data center




Poor Disaster Recovery Plan




Testing or Demonstration needs




Companies experiencing Growth or Retraction




24 x 7 Operations




Companies with home based workers




Experiencing Budget constraints (need to do more with less)


There are some REAL benefits

to Cloud Computing.

Fact #4




Access to better systems




Improve availability (Disaster Recovery)




Reduce infrastructure management needs




Resolve problems related to updating/upgrading



Pay only for what we use




Hardware, Software and Maintenance savings




Lower labor and energy costs




Reduce support and management needs




Reduce space required to house infrastructure




Able to scale IT resources to meet needs




Take advantage of latest functionalities




Rapid deployment

Security is a major consideration when deploying

Cloud Computing, but Cloud Computing

MAY be more secure than on
-
premise computing.

Fact #5


Security




Security and Privacy




Performance




Technology Immaturity




Regulatory Compliance




Integration


Fact #1: “Cloud Computing” means different things to
different people, and that’s OK.


Fact #2: Cloud Computing is overhyped right now but it
is definitely a shift in computing.


Fact #3: Cloud Computing is not a “one size fits all”
solution.


Fact #4: There are some real benefits to Cloud
Computing.


Fact #5: Security is a major consideration when
deploying Cloud Computing, but Cloud Computing MAY
more secure than on
-
premise computing.

Recap



Thank you.
