VMware and

Cloud Computing

An Evolutionary Approach to

an IT Revolution

During the past 40 years, information technology has undergone many

revolutions in how applications and data have been delivered to users.

Mainframes provided a centralized computation facility where end users

consumed resources on a shared basis. Client-server architectures oered

ﬂexibility and lowered computing costs while bringing more power to the

desktop. Mobile computing introduced the notion of anytime, anywhere

application access from a laptop or handheld device. Now cloud computing

oers a new approach that will enable you to deliver IT services on demand.

Yet the challenges with IT revolutions and the technology vendors leading

them are always the same. They require you to throw away working

infrastructure to pursue new initiatives—until now. Until VMware.

Why Cloud Computing? Why Now?

Business stakeholder demands on IT are increasing. Every business decision

impacts IT, and accelerating market forces reward ﬁrst movers. Yet most

enterprise applications and services are built on top of tightly coupled

technology stacks that are challenging to change and costly to manage.

Provisioning a new email server or business intelligence engine, for example,

can require months of waiting just for hardware purchases and system

image conﬁgurations.

Caught between shrinking resources and growing business needs, organizations

are looking to cloud computing to provide a more ecient, ﬂexible and

cost-eective model for computing—one that allows IT to operate much more

eciently and respond faster to business opportunities. The goal is to enable IT

as a Service, and cloud computing provides the technical architecture to deliver it.

Why VMware?

VMware is the global leader in virtualization and cloud infrastructure. Today,

more than 190,000 customers and 25,000 partners rely on VMware solutions

to achieve their business goals. VMware oers a unique, evolutionary path to

cloud computing that reduces IT complexity, signiﬁcantly lowers costs and

enables more ﬂexible, agile service delivery.

A New Era in IT

VMware enables you to energize

your business, while saving energy—

ﬁnancial, human and the Earth’s.

Our customer-proven solutions

ensure the following:

Eciency Through Utilization

and Automation

VMware solutions help you achieve

lower total cost of ownership (TCO)

while minimizing unnecessary

IT infrastructure investments,

management and maintenance

resources, and system lock-in.

With VMware solutions, you adopt

a more cost-eective, self-managed,

dynamically optimized environment

for the most ecient delivery of

IT services.

You gain additional ﬂexibility

by developing and deploying

applications that can run in your

datacenter or at a cloud service

provider. You move toward an

infrastructure that uses policy-driven

management and automation

to monitor itself, self-optimizing

for load and demand on the

applications, based on usage.

Agility with Control

VMware solutions provide easy,

self-service access to dramatically

simplify IT services provisioning

and deployment, so you can

respond more quickly to business

needs. At the same time, they allow

you to put policies in place that

implement business and governance

requirements, giving IT sta the

control it needs to minimize business

and regulatory risk. VMware

also leads the way in security for

virtualization, so your policies are

always applied to a secure virtual

container for your virtual machines,

wherever they run. This eliminates

having to constantly reconﬁgure

static security infrastructure for your

dynamic computing environment.

Proven

In addition to serving as a

secure foundation, VMware core

virtualization solutions ensure

portability between internal

datacenters and external hosting and

service provider clouds from VMware

vCloud™ partners, enabling your

applications to run with little or no

modiﬁcation internally or externally.

Beyond infrastructure, the VMware

cloud application platform allows

your developers to create portable

cloud applications that further

enhance your ability to respond to

change. You can extend this agility

to end users by leveraging VMware

solutions to dynamically provision

and manage cloud-ready IT services

securely across any device. The

beneﬁt: on-demand access for an

on-demand workforce.

With VMware solutions, you maintain

full control over the availability,

reliability, scalability, security and

service level agreements (SLAs) for all

workloads, from enterprise to desktop

applications, from the most mission-

critical applications to the most basic.

Freedom of Choice

VMware solutions provide you with

the ﬂexibility to retain your existing

operating system and application

stack, yet deploy it internally or

externally with any vCloud service

provider. Using VMware solutions,

you can continue to support

traditional systems, while removing

many of the headaches associated

with them—system porting, security

patches and more. You also gain

more predictable performance.

You have the freedom to select

how much you virtualize, and how

and when you move to a cloud

deployment model. VMware solutions

ensure application mobility and

portability between clouds within a

common management and security

model. They are based on open

standards, including the Open

Virtualization Format (OVF), which

has been adopted as an American

National Standards Institute (ANSI)

standard. They also extend to a

large ecosystem of more than 2,600

service providers.

VMware continues to invest in

a broad, global ecosystem of

hardware and software providers

to maintain compatibility with your

existing investments. This ensures

that thousands of x86 applications

and workloads, as well as dozens

of dierent operating systems, run

on VMware solutions. Moreover,

because of this investment, most if

not all of your existing applications

are cloud-ready today.

You can also deliver more freedom

to users without sacriﬁcing yours.

VMware solutions enable end

users to consume IT services from

traditional applications, onsite cloud

applications and vCloud oerings

from external service providers,

and provide rapid access to their

data anytime, anywhere. Meanwhile,

there is freedom for you to manage

by service level and policies across

platforms and devices.

With cloud computing’s promise

of making IT services available on

demand, you may no longer wonder

why you should move to the cloud but

rather how you can achieve its beneﬁts.

With VMware, the way is clear.

application or service layer from

the underlying infrastructure or

resource layer to provide a much

more scalable, ecient and elastic

model for delivering IT services. You

can dramatically reduce costs in the

infrastructure or resource layer by

aggregating the resource needs of

the entire organization and using

the shared infrastructure to drive

capacity utilization higher than ever.

At the application or service layer,

cloud computing oers a new service

consumption approach that applies

standardization and automation to

enable rapid service provisioning.

Instead of waiting for manual IT

procurement and provisioning

processes, lines of business are

able to consume services exactly

when they need them. Meanwhile,

IT retains control over policies and

billing that govern service usage.

Only VMware oers a pragmatic path

that lets you encapsulate legacy

applications and move them to a

modern cloud computing environment

with ensured security, manageability,

quality of service and compliance.

Using VMware solutions, you can

evolve to an on-demand, highly

available and highly secure cloud

computing model—with automated

service levels and standardized

access—to immediately deliver cost

eciency and business agility.

During the process, you do not

need to “rip and replace” existing

infrastructure. With VMware, you

can leverage current investments to

transform an internal datacenter into

a private cloud environment. You can

build and deploy a private cloud today

that yields improved IT eciency and

agility while enhancing security and

choice. At the same time, deploying a

private cloud on the VMware platform

provides a practical path to the highly

scalable, high-performance public

clouds being built by recognized

service providers leveraging the

VMware platform.

By adopting the leading platform

chosen by the largest number of

enterprises and service providers,

you have the choice to place any

of your workloads in the optimal

location (a private or public cloud)

while fully retaining the ability

to move workloads between or

across private and public cloud

infrastructure—leveraging a hybrid

private-public cloud environment.

Assessing Applications

for the Cloud

The VMware approach to cloud

computing is not about a single

technology purchase or an abrupt

disruption to the business. It is a

path that you can follow based on

your environment today. Before

you achieve the full evolution to

cloud computing, there are

tangible, immediate steps that

you can take to start the process,

including identifying the dierent

types of workloads currently in

your datacenter.

Since virtualization is the foundation

for cloud computing and IT as

a Service, the ﬁrst task for any

organization transitioning to the

cloud is to virtualize the majority of

its environment, including business-

critical applications. This will allow

you to guarantee service levels more

easily and economically.

The second step is to turn your IT

department into an agile and user-

friendly internal service provider.

This requires exposing IT services

to internal users through Web-

based portals as a fully automated,

catalog-based service. Whenever

internal users need IT services, they

should be able to get them as easily

as ﬁnding and downloading an

application from Apple’s App Store.

Yet where should you begin enabling

fully automated self-service? What

are the best initial application

candidates for this approach? The

answer is relatively simple: the best

candidates are those applications

most frequently requested by users,

which tend to be the following:

1. Transient apps – Applications

that will have a rapid rate of

provisioning, cloning, reallocation

and so on, for example, a staging

or preproduction development and

test environment.

2. Elastic apps – Applications where

the demand for resources will vary

greatly over time, so users will

request adjustments to the

application resources, for example,

scientiﬁc computation or anything

with seasonal transactions.

3. “Long tail” apps – Applications

that never get prioritized by

IT organizations, for example,

a customized Web farm for

an extranet.

VMware customers have prioritized

these types of applications for self-

service due to the high rate of change

they experience with them. Often,

the bulk of requests that consume

IT sta time are generated by ad

hoc workloads rather than business-

critical production applications. Plus

ad hoc workloads cause the biggest

cost and administrative headaches

for IT. Applications such as these

will beneﬁt considerably from being

served out of a cloud environment

and can drive immediate value to

the business.

“Strategically, server

virtualization is an IT

modernization catalyst

that will change how IT

is acquired, consumed,

managed, sourced and paid

for. Virtualization will even

change how businesses

innovate and grow,”

writes Thomas Bittman,

VP Distinguished Analyst

at Gartner. “Done well,

server virtualization makes

fundamental changes that

can lead an organization

down the path of private

and public cloud computing.”

Cloud Computing,” Thomas Bittman, October 29, 2009.
