2012 Year of the Cloud? High levels of confusion

Just what is cloud computing?

Major areas of concern

End-user experience

Security

Business models

Too much choice

Where are the realcloud

standards? Inertia

My applications are OK, thanks

The end result is hybrid.

Cloud perceptions

0% 10% 20% 30% 40%

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

EUE actions Use end-to-end measurements

Use MOS for applications not just VoIP

Keep data and business logic close together

Use hybrid virtualisation models

Wide area network acceleration

Packet shaping

Traffic management

Caching

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


12/20

Quocirca 2012

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


13/20

Quocirca 2012

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


14/20

Quocirca 2012

The process approach We have a problem with our

customers

Why? Where?

Address the issue

Wrong type of prospect?

Not getting full value?

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!


16/20

Quocirca 2012

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


17/20

Quocirca 2012

Plan A Carry out gap analysis between where you

are and where you need to be

Identify what existing applications andfunctionality can be saved

Identify what is missing

Decide on where the missingfunctionality should come from

Choose method of aggregation

Implement, review and change as

needed


18/20

Quocirca 2012

Plan B? How to deal with lock in?

What if internet connectivity is down?

What to do when a component of thechain changes functionality?

What to do around changing business

models?

What if any part of the chain goes bust?


19/20

Quocirca 2012

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
