Cloud Computing – clearing the fog.
Cloud Computing – a definition…
A standardised IT capability, (services, software or infrastructure)
delivered via Internet technologies in a pay-per-use, self-service way
…and an analogy for the vision…

Rapid Evolution
The Cloud is a lot like the iPhone…
Cloud Features – providers, integrators,
tools, products services
iPhone apps, iPhone OS
releases, iTunes features

…but like the iPhone its also over-hyped!

There are benefits…
 Reduced Costs – if done right
– Better alignment of budgets with application demand
– Deliver applications without raising the capex budget
 Improved time to application deployment
 Better ability to handle demand peaks
 Ability to share data with reduced security risk

…and also risks
 Multi-tenancy clouds may clash against security, privacy and compliance requirements
 Economics of the new charging model may not stack up
 Risk of vendor lock in
 Some degree of reliability and control is sacrificed
 Integration of Cloud applications may prove difficult and expensive down the line
 Standardised models and workloads may limit custom applications

What interoperability standards
does a supplier support?
Maintaining alignment with
company’s technical strategy
Contract terms
Cost comparison
Third party integration costs?
Non IT procurement exposing the company to
some or all of these cloud issues – need for
greater/tighter internal governance

…and it needs to be right for YOU!
There is no ‘one size fits’ all – every organisation is
different. What you see when you look at the cloud
depends on the type of business you are…
 There are multiple obstacles to overcome in adopting Cloud Computing and the risks
are poorly understood, but the potential benefits could be significant
 Organisations must ensure that they are Cloud-ready and evaluate opportunities by
applying a structured framework
– Identify potential candidates for Cloud-based services
– Can I do it, and if so where should I start?
– Is it worth doing?
– Does it limit my future options?
Will you even need an IT department in 5 years time?
