• On-demand self-service
• Broad network access
• Resource pooling – multi-tenanted

18. The Nutshell (again)
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
22. 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
24. 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
26. Rapid elasticity: scale fast
No need to provision for peaks
No idle assets – 100% ROI
Less reliance on CapEx
27. Measured service

28. 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

32. 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 ?
33. 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 ?
