Cloud Computing Nutshell

Is a way to outsource ICT, with its own characteristics

• On-demand self-service

• Broad network access

• Resource pooling – multi-tenanted

• Rapid elasticity – scale fast

• Measured service

Entered into if the benefits outweigh the total costs and risks

Vendor needs to schedule clients

The Nutshell (again)








Self-service

Rapid deployment

Uncontrolled proliferation

i.e. the Internet

Deploy and access „anywhere‟

Totally dependent on the Internet – a best endeavours network

Another hole in your corporate perimeter

Resource pooling: multi-tenanted

Resource pooling: multi-tenanted

Everything hosted on the cloud

Vendor manages technology and operations

Benefit from volumes of scale

Manage service and outcomes

No customisation

Vendor dictates upgrades

No need to provision for peaks

No idle assets – 100% ROI

Less reliance on CapEx

Measured service


Measured service

Pay for what you use

Pay as you go

Direct linkage between usage and cost – management tool

Smooth expenditure profile

Hard to unwind Capex-to-OpEx shift

Fad or Trend ?

Data Legal

Obligations

Data Obligations

Data is outside your corporate custodianship – maybe off-shore.

How secure is your data? – total reliance on vendor

XaaS – you may not have the right to access the underlying data

Data ownership

Can you meet all of your legal obligations ?

Legal Obligations

Large cloud computing providers are multi-nationals

What contract law applies ?

What data protection laws apply ?

What 'lord of the manor' rights exist ?

Can you meet all of your legal obligations ?
