Now, Peter Coffee from salesforce.com is up. He believes that "Enterprise cloud computing implies API leverage". Start conversation with the function you want to perform, not the underlying technology.
He has a quote up from William S. McNee, of Saugatuck Technology "On-premise computing is going to drop-off a cliff" (or something close to that, the slide changed)

| database as a service |
| infrastructure as a service |

many tech trends oppose governance goals:
- processing availability is enemy of encryption
- connectivity provides attacker opportunities and tools
- storage, ever growing risk of larger data losses (thumb drives, laptops, email)
Service models offer greater leverage:
- granular management of roles & privileges
- data is in the cloud, not carried around and subject to physical loss
- [one more, sorry...]
Now, talking of developer productivity using force.com vs. java development; overall project cost 30-40% less
Points to charts and metrics from the economics of the cloud post on O’Reilly.
PaaS puts IT spending back in balance. Conventional IT model front-loads capital expenditure on infrastructure. PaaS enables preparation for upturn. Build now without big up-front investment, scale at upturn via PaaS.
"Do not mistake the consumer Web for the enterprise cloud". It’s not like putting your G/L on facebook.
