APPLICATION
Automated and
Managed by the Public
or Private Cloud Offering
Managed and
Controlled by Customer
(IT, Dev, or User)
IaaS PaaS SaaS
Increased Control
Increased Automation

5. A Cloud Application Platform
Code Deploy Run
Save Time and Money
Code your app
Push-button
Deploy, and
your App is
running in
the Cloud!
