The document defines cloud computing by explaining the three service models - Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). It notes that SaaS provides ready-to-use applications, PaaS allows for browser-based development and seamless deployment, and IaaS provides on-demand infrastructure resources. The document uses rhyming phrases and analogies to define cloud computing and make the concepts more accessible.

The Cloud!
On Premise

10. I am sure your head says big deal!
That is just how you feel …
The Cloud still seems like such a buzz …
Why are people making such a huge fuzz?

11. The premise of the cloud is not to just
move stuff out
It should be defined better without a
doubt
Is there a better possibility?
To define its true ability?

12. It is all about delivery …
SaaS Platform Infrastructure
Software as a Service (SaaS)
– Applications that are ready for use
– Examples: CRM, Email, Collaboration
– Units: User, Account, or Transaction

– Examples: Database services, Workflow applications, Social Networking platforms
– Units: Instances

14. You can customize, but you are in charge
Software Platform IaaS
Infrastructure as a Service (IaaS)

three categories:
Configuration

PaaS
IaaS
Customization

17. CLOUD OR UTILITY
COMPUTING?
Get rid of the buzz …

24. Need an instance or a node?
How about two?
Maybe more? What say you?
Or just may it be the tale
On what to do, when number FOUR
Shows up at your DOOR

25. IN SUMMARY
We’ll say Presto!
