Don't Know
It has no place in the future of my
organisations IT platform
It is just a passing fad to be overtaken by
something new in a few months time
It is purely a simple evolution of earlier
technology approaches
It will be an important part of my
organisations IT platform along with
existing approaches
It is a complete game changer that will
transform how IT and organisationswork together

If you are going to adopt cloud, whatbest matches your plans?
0% 10% 20% 30%
Don't know
We have no plans to adopt cloud
We will only adopt public external cloud services
We will create one or more private clouds tosupport the organisation, butnot use public clouds
We will use private clouds using external data
centre facilities
We will use a mix of internal and/or external
private clouds, mixed with public cloud services as
required

Cloud security
0% 10% 20% 30%
Don't know
Issues around security are a show-
stopper
Security is top of mind while looking at
cloud
Security is an issue - but no more than
other areas
Security needs a different approach -
but will be easy to deal with
Cloud security is no different to other ITsecurity

Cloud security Slow move in perceptions
Its not about the platform
Its the information that matters
Taxonomise
Prioritise
Encrypt at rest and on the move
See security as an enabler nota constraint

Consumerisation Lock down is no longer an option
An individuals choice of device is alifestyle statement
Device standards are dynamic
Screen size
Function
Adoption of industry standards dejure and de facto
Device lifecycles are compressed
12-18 months is common

Dealing with consumerisation Virtualise
Use the device mainly forviewing
Sandbox
Abstract the function
Define minimum standards
What capability is necessary?
Airlock and enforce
Install anything that is missing

The death of the application? We have a problem with our
customers
Buy a CRM application
Why?
Applications can be inflexible,
constraining
Do it my way
Cloud offers many different functions
Better domain expertise
Better focus

This is a process issue not anapplication one
Get the process right
Apply technical functions tosupport the process

Licensing Cloud is not necessarily a subscription-only service
Do you still want license plus maintenance?
Cloud can cover a lot of different approaches
PaaS you maintain control over a lot of the stack
IaaS you maintain control over the softwareapplication/main functions
SaaS You are probably looking at subscription
E/XaaS you are almost definitely looking atsubscription
Its a dynamic environment go for what fits your needs
Beware vendors with per core licences!

The need for aggregation No single cloud provider can be a complete one stop
shop
Options are:
Dont use cloud
Use one cloud provider with all other functionality
provided and integrated in-house
Use multiple cloud providers and integrate on a one-by-one basis
Use multiple cloud providers with one being a prime
contractor responsible for integration Use a specialised cloud aggregator to deal with all
cloud integrations

Conclusions The Good side of cloud is that it is more efficient, more
dynamic and more capable of supporting the business
The Bad side of cloud is the lack of de facto standards and too many emerging de jure standards
The Ugly side of cloud is the poor offerings,capabilities and overall messaging of many of thevendors involved
Cloud will be a game changer just make sure that yougo in with your eyes open
