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

Cloud Services
Business Process as a Service
• E.g. HR system (legally compliant)
Software as a Service
• E.g. Email, Social networking, CRM
Platform as a Service
• E.g. Payments, web site and databases
Infrastructure as a Service
• E.g. Networks, servers and storage

On-demand self-service
Face-to-face engagement process
Broad network access?
Need to put the network in, or use dial-up
Resource pooling
Rapid elasticity?
Vendor needs to schedule clients
Measured service
Cloud like – just
Internet provides the network
Web 2.0 enables self-service

Self-service
Rapid deployment
Uncontrolled proliferation
Broad network access

Broad network access
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
Rapid elasticity: scale fast

Rapid elasticity: scale fast
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 ?
