Just hot air?
The term cloud computing has
been much hyped in recent
past.
Indeed everyone seems to
mean something different when
they talk cloud.
For one, cloud has long been
the graphic used for „any
network‟ connecting two
computers.
5
Computer scientists would see it as
the culmination of a long line of
contributing technologies.
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.
Cloud is web based SaaS
+
web based, hosted dev platform
Some vendors, like
SalesForce, argue that cloud is
the whole future of IT.
Google IS the cloud
Others, like Google, define
cloud as just – what they do.
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‟
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‟
Cloud is insecure
Loss of IT control
Limited SLAs
A Threat
But it‟s just not that simple
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‟
Storage
$0.15/GB/mo
vs.
$3.75/GB/mo
Servers
1 admin/20,000
vs.
1 admin/100
Network
$10/megabit
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.
Standardisation
But they are misleading for the
enterprise as they result from
massive standardization at the
core of each vendor‟s business
model.
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.
IaaSInfrastructure as a Service
Let‟s start by talking about
Infrastructure as a Service or
IaaS.
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.
“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.
• 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.

Unisys, SGI, Samsung, Sun, VA
Systems, Red Hat, Novell, VA
Linux, DoD, NSA (42 orgs) ”

+ 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.
Sounds good so far? IaaS is
more complex than it may
appear. IaaS cloud vendors
mean many different things by
„cloud‟.
Some emphasize base level
virtualization – virtual servers,
virtual storage, and virtual
networks.
Others emphasize resource
management, multi-tenancy (in
all its forms), usage monitoring,
and optimizing across the farm.
Still others are mainly about
application management,
which components work where,
and how they need to interact.
And some are mainly about
providing access and
automation in the cloud.
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.
What else?
SaaSSoftware as a Service
Software as a Service or SaaS
also brings important “cloud”
ideas for the enterprise.
Citrix is the fifth largest
external SaaS vendor
globally with the Citrix
Software as a Service
offerings.

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
Delivering Enterprise IT as a Service
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.
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
C3
(SaaS + IaaS)
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.

Here‟s a simple schematic
showing how it might deployed
for cloud use (inside or outside
the datacenter)
Recent additions to C3 include:
A virtual appliance version of
our celebrated NetScaler
appliance.
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.

Recent additions to C3 include:
XenApp and XenDesktop, as we‟re
recognized that application delivery
is an important cloud task. All of
these contribute to the broader
picture.

Enterprise
Cloud
Enterprise Cloud is about new
operating models that leverage
the flexibility and agility of
SaaS and IaaS.
Windows Apps
Enterprise Cloud is about
Windows applications being
delivered as SaaS.
“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.
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.
