3. Cutting through the hype:
Cloud differs from the
traditional approach to
outsourcing
– On demand provisioning
– Pay as you go – pay as
you grow
– Much lower cost as
WHAT IS economies of scale are
assumed
CLOUD? – Near infinite capacity
Cloud is not virtualisation
Cloud is not finance / off
balance sheet financing
THE CIO’s CLOUD HANDBOOK 3
4. What should it be about:
The ability for
organisations to stop
solving all IT problems by
themselves
It’s not just about sharing
resources
It’s about pushing risk out
of the business
WHAT IS
CLOUD? If I took every component
of what we use in our data
centres and provided it as a
service…
…it would not be cloud
THE CIO’s CLOUD HANDBOOK 4
5. Cloud Rep v Enterprise CIO
How much Cloud do you want to buy ?
We have scale and can easily migrate your user base
You can move from Capex to Opex
Look at how much we do
Look how big our data centre is
THE CIO’s CLOUD HANDBOOK 5
6. Cloud Rep v Enterprise CIO
Flash Migrations are Utopian
You don’t need to decommission all your IT assets
One vendor will never have all the answers
Why you can’t trust your ISP
THE CIO’s CLOUD HANDBOOK 6
7. Cloud Rep v Enterprise CIO Part 2
(I see you’re informed…)
How much Private Cloud do you want to buy?
We manage thousands of virtual servers and can build you your own pod
Private Cloud solves the customisation limitations of Public Cloud
The infrastructure is dedicated to you
THE CIO’s CLOUD HANDBOOK 7
8. Cloud Rep v Enterprise CIO Part 2
How much will you really lower your costs by substituting your
existing enterprise tools?
Private Cloud has structural Rules as well
Dedicated Infrastructure does not a Private Cloud make
Your line of business personnel may not have the expertise for self-service
THE CIO’s CLOUD HANDBOOK 8
10. Lesson 1
STAY
AGILE
You need an orchestration
layer that is vendor
agnostic
API’s are meaningless if
they are tied exclusively
to Private Cloud or a
particular public cloud
THE CIO’s CLOUD HANDBOOK 10
THE CIO’s CLOUD HANDBOOK 10
11. Lesson 2
EMBRACE
MULTI-
TENANY
Hierarchical domains are
too rigid
Think of your
infrastructure as ‘Pods’
– Some Pods will be
existing infrastructure
– Some will be offsite
Private Clouds
– Some will be Public
Clouds

– Make sure you can apply
chargebacks

Why you can’t trust your ISP – ISP’s are governed by legislation which compels them to comply with government surveillance e.g. monitoring and interception of telecommunications act
API – Application Programming interface
ThinApps – Application Virtualisation from Vmware or AppV from Microsoft
