Transcript of Cloud Computing: Living in the Cloud

"The first rule of cloud computing
is to use cloud presentation" cloud computing: living in the cloud What do you expect when you
flick a Light Switch on? Did you consider
Resourcing?
Production?
Infrastructure?
Delivery? Yet, you expected
Always turn on?
Cost as much as you use? The "Utility Model" Expectations
Starts with Switching On
Ends with Switching Off Contract
Plugging in the Appliance Consumption is Disconnected From
Resourcing
Production
Infrastructure
Delivery Cost
Pay for what you use
Share the Infrastructure cost { Cloud
