...a model for enabling convenient, on-demand network access to a shared pool ofconfigurable computing resources (e.g.,networks, servers, storage, applications, andservices) that can be rapidly provisioned andreleased with minimal management effort orservice provider interaction.

- National Institute of Standards & Technology (NIST)

AN OFFICIAL CLOUD DEFINITION

WHERE CLOUDS ARE HEADED

Resource abstraction and pooling

Network-centric

Simple, fast provisioning of resources

Elastically provisioned resources

Utility pricing

A CLOUD TAXONOMY

IaaS (Infrastructure as a Service)

Provision processing, storage, networking,

and other computing resources

Deployer configures and maintains operating

systems, other software, and logical

application wiring

Examples: Most private clouds, Amazon Web

Services, IBM Cloud


6/23

6

PaaS (Platform as a Service)

Typically additional services/abstractionlayered on IaaS foundation

Simplify development (e.g. app server

services)

Simplify operations (e.g. scaling with grid)

Examples: Google App Engine, Force.com


7/23

7

SaaS (Software as a Service)

Direct consumption of an application by end

users

No inherent relationship to IaaS or PaaS but

underlying infrastructure affects reliability

and scalability of service

Examples: Salesforce.com, Intuit QuickBooks

Operated solely for asingle organization

Typically internally hosted

but may be operated by a

third-party

Provides the greatest

degree of control over

service levels, compliancerequirements, etc.

Infrastructure or platform

made available to general

public or large industry

group

Limited view into and

control of the underlyingphysical infrastructures

location and type

Applications run in ashared, multi-tenant

environment with those of

other organizations

Term typically used to

refer to a blending of

public and private clouds

Typical use case is

utilizing a public cloud as

overflow capacity for aprivate cloud

Assumes level of

interoperability betweenprivate and public

implementations

business problems.

Provide new services despite budget

limits

Increase enterprise agility

Bond more tightly with customers

Improve service levels

Reduce capital requirements

Increase operational efficiency

THE MOST POWERFUL SHIFT IN ENTERPRISECOMPUTING IN THE LAST DECADE

THE CLOUD IS THE

WHAT DOES THE CLOUD REALLY MEAN TO YOU

ENDING WASTE The old way:

Overbuying computing capacity, based oninfrequently used peak demand.

Purchasing, installing, and provisioning a server

for each new request in the organization.Maintaining it for years to come.

Responding slowly to business opportunities orthreats because it takes a long time to add orchange apps and infrastructure.

Having to manage and support many differentinfrastructure platforms.

SEIZING

OPPORTUNITY

The new way:

Buying computing capacity as you need it,when you need it

Responding to demand for new services in

minutes, not months.

Meeting SLAs by using all available computingresources to meet users' requirements.

Efficiently managing the diverse systems andplatforms you already have, without having to

replace them.

Using IT to drive innovation and respond tochanges in the business.

Cloud computing is a collection oftechnologies that infuse characteristics like

abstraction, elasticity, automated, anddynamic into traditional computing, which isbetter described by words like hardwired,fixed, manual, and static. It builds on, and

adds automation to, virtualization.

Is it safe?

Is it rip-and-replace?

Will it lock me in?

Will the service perform

as promised?

Complexity of configuring servicesdisappears

Users get what they need when they need it

Red Hat is building the foundations of real

clouds today

Adopt the cloud at your own pace: evolution,not revolution

No other vendor has the breadth of softwareneeded to build open clouds

Open source delivers more innovation,flexibility, reach, and value than anymonolithic stack

RED HAT'S CLOUD COMPUTING VISION

Create the datacenter of the future

That is open and

interoperable

That preservesexisting ITinvestments
