Just hot air?

The term cloud computing has

been much hyped in recent

past.

Page 3: Cloud Computing And Citrix C3 - July 2009

Indeed everyone seems to

mean something different when

they talk cloud.

Page 4: Cloud Computing And Citrix C3 - July 2009

For one, cloud has long been

the graphic used for „any

network‟ connecting two

computers.

Page 5: Cloud Computing And Citrix C3 - July 2009

Computer scientists would see it as

the culmination of a long line of

contributing technologies.

Page 6: Cloud Computing And Citrix C3 - July 2009

Cheap, utility-supplied

computing will ultimately

change society as profoundly

as cheap electricity did

Others, like Nicholas Carr,

have a „utopian‟, user oriented

view of cloud computing.

Page 7: Cloud Computing And Citrix C3 - July 2009

Cloud is web based SaaS

+

web based, hosted dev platform

Some vendors, like

SalesForce, argue that cloud is

the whole future of IT.

Page 8: Cloud Computing And Citrix C3 - July 2009

Google IS the cloud

Others, like Google, define

cloud as just – what they do.

Page 9: Cloud Computing And Citrix C3 - July 2009

Cloud is ease of use

It‟s every cool web page

It‟s Google mail

It‟s SaaS

It‟s EASY

For the end user, cloud is

synonymous with „nice web

application‟

Page 10: Cloud Computing And Citrix C3 - July 2009

Cloud is flexibility of resources, available on demand

Cloud is dynamically scalable

Cloud is automated

Cloud is IT nirvana!

For Enterprise IT, cloud promises

to make IT „easy‟

Page 11: Cloud Computing And Citrix C3 - July 2009

Cloud is insecure

Loss of IT control

Limited SLAs

A Threat

But it‟s just not that simple

Page 12: Cloud Computing And Citrix C3 - July 2009

1. Simple

2. Unexpected

3. Concrete

4. Credible

5. Emotional

6. Stories

So why so many disparate

views?

Cloud computing is an idea

„made to stick‟

Page 13: Cloud Computing And Citrix C3 - July 2009

Storage

vs.

$3.75/GB/mo

Network

vs.

$500/megabit

Apps

1 image x 1M users

x 4 upgrades/yr

vs.

230 apps x 5 versions

x many upgrades

One of the reasons „cloud‟ is so

popular is that enterprise IT sees these

numbers from cloud providers as

extremely attractive.

Page 14: Cloud Computing And Citrix C3 - July 2009

Standardisation

But they are misleading for the

enterprise as they result from

massive standardization at the

core of each vendor‟s business

model.

Page 15: Cloud Computing And Citrix C3 - July 2009

Cloud

Software as a Service

Infrastructure as a Service

Platform as a Service

Here are some commonly

agreed cloud categories.

Only IaaS requires System

Virtualization.

Page 16: Cloud Computing And Citrix C3 - July 2009

IaaSInfrastructure as a Service

Let‟s start by talking about

Infrastructure as a Service or

IaaS.

Page 17: Cloud Computing And Citrix C3 - July 2009

Elastic Compute Cloud

• from $0.10 per VM hour

Simple Storage Service

• $0.15 per gig stored

• $0.17 per gig transfered

Amazon has been a pioneer of

IaaS with their Elastic Compute

Cloud and Simple Storage

Service.

The Amazon cloud has enabled a

new wave of innovation.

Page 18: Cloud Computing And Citrix C3 - July 2009

“30 employees. More than

300,000 paying customers.

288,000,000 photos.”

NO INFRASTRUCTURE

For example, SmugMug have been

able to scale tremendously without

any of their own infrastructure

through using Amazon Servers and

Storage.

Page 19: Cloud Computing And Citrix C3 - July 2009

• New York Times

• 4TB of TIFFs

• To 1.5TB of PDFs

• 100 EC2 Xen VMs

And burst computing by the

New York Times in converting

historical images for use on a

„retrospective‟ web site.

+ XenServer + 100% compatible

with Hyper-V

These capabilities are enabled by

system virtualization and, in most

cases, by the Xen Hypervisor which is

at the heart of Citrix XenServer as

well as at the heart of most public

clouds.

Page 21: Cloud Computing And Citrix C3 - July 2009

Sounds good so far? IaaS is

more complex than it may

appear. IaaS cloud vendors

mean many different things by

„cloud‟.

Page 22: Cloud Computing And Citrix C3 - July 2009

Some emphasize base level

virtualization – virtual servers,

virtual storage, and virtual

networks.

Page 23: Cloud Computing And Citrix C3 - July 2009

Others emphasize resource

management, multi-tenancy (in

all its forms), usage monitoring,

and optimizing across the farm.

Page 24: Cloud Computing And Citrix C3 - July 2009

Still others are mainly about

application management,

which components work where,

and how they need to interact.

Page 25: Cloud Computing And Citrix C3 - July 2009

And some are mainly about

providing access and

automation in the cloud.

Page 26: Cloud Computing And Citrix C3 - July 2009

Operational efficiencyOff-premise

On-Premise

The key promise of IaaS is to bring

improved operational efficiency from

virtual server agility.

While much of the rhetoric focuses on off-

premise cloud, on-premise (or private)

cloud offers immediate benefits to

enterprise IT.

Page 27: Cloud Computing And Citrix C3 - July 2009

What else?

Page 28: Cloud Computing And Citrix C3 - July 2009

SaaSSoftware as a Service

Software as a Service or SaaS

also brings important “cloud”

ideas for the enterprise.

Page 29: Cloud Computing And Citrix C3 - July 2009

Citrix is the fifth largest

external SaaS vendor

globally with the Citrix

Software as a Service

offerings.

Application Delivery=

Enterprise SaaS

Abstract connectionHigh-fidelity experienceCommon security model

etcetc

There are enormous benefits

from treating all enterprise

applications as SaaS – as

applications to be delivered to

end users on demand.

Where Does Citrix Fit? Citrix Delivery Center

XenDesktop · XenApp · NetScaler · XenServer

Citrix has long been about turning

Enterprise applications into a

service. In a very real sense,

bringing delivery abstraction to

every application.

From a TCO and ROI

perspective this approach

brings formidable

benefits.

Page 33: Cloud Computing And Citrix C3 - July 2009

However the long term

effects are potentially more

important. Using an

application delivery

“mediator” between your

enterprise architecture and

application architecture

makes the organization

“change friendly” by reducing

inertia.

Citrix Cloud Center addresses

both SaaS and IaaS.

Citrix Delivery Center

[but for the cloud]

C3 is exactly the same technology

that Citrix sells for the Enterprise,

but with a pricing model that‟s more

appropriate for the cloud.

Recent additions to C3 include:

A virtual appliance version of

our celebrated NetScaler

appliance.

Page 38: Cloud Computing And Citrix C3 - July 2009

75% of Internet Users Each Day

The physical NetScaler appliance is

heavily used by internet companies

globally to optimize their web

applications to the extent that 75%

of all internet users touch the

technology daily.

these contribute to the broader

Enterprise

Cloud

Enterprise Cloud is about new

operating models that leverage

the flexibility and agility of

SaaS and IaaS.

Page 45: Cloud Computing And Citrix C3 - July 2009

Windows Apps

Enterprise Cloud is about

Windows applications being

delivered as SaaS.

Page 46: Cloud Computing And Citrix C3 - July 2009

“Cloud-burst”

Enterprise Cloud is about Cloud-bursting;

for example automatically load balancing

application delivery sessions to the cloud

when the physical XenApp farm is at it‟s

limit.

Page 47: Cloud Computing And Citrix C3 - July 2009

BridgeApps in cloud; Data stays on premise

Enterprise Cloud is about the

capability to keep your data on

premise and your applications in

the cloud.
