Service ProviderOwned and managed, Accessed via the web, Pay for what you use.
Privately owned And managed with Restricted access (but Could be externallyhosted)
Interoperable combination
of private and public cloud.
Types of Clouds
Software-as-a-Service (SaaS) (hosted apps)
Platform-as-a-Service (PaaS)(dev platform, apps middleware)

“What is your main driver in moving to private cloud?”
Agility / Speed55%
Who is likely to build a private cloud?
Dynamic environmentPro-activeIT as business enablerRapid growthTechnically sophisticatedSignificant new in-house developmentMajor virtualization adoptionSmall
Static environmentReactive
Focus on minimizing IT costsSlow growth
Low skills/technical sophisticationPackaged apps and SaaS
Limited, tactical virtualization useLarge
Unlikely to build Private Cloud

Platform-as-a-Service:Hosted or on-premise
Where does SaaS tend to fit?
• Relatively standardized
• Modest integration requirements
• Non-differentiating
WHAT ABOUT SECURITY?
Some things don’t change with cloud
If your security practices suck in the physical realm, you’ll be delighted by the surprising lack of change when you move to cloud.

(A few) implications
• Delivery of “as-a-service”
• Commoditization
• Domain expertise still valuable
• Lower CAPEX for new businesses
• New software architectures leverage ecosystem of services
• But introduce dependencies on third-parties
• Access increasingly mobile & multi-device
