Cloud Computing
= Software as a Service
(pay-as-you-go)
+ Platform as a Service
+ Infrastructure as a Service
 Cloud Software as a Service (SaaS)
Use Provider’s Applications Over a Network (Ex: CRM,ERP,SCM)
 Cloud Platform as a Service (PaaS)
Deploy Customer-Created Applications To a Cloud
(Ex: Microsoft /.Net , Linux/J2EE )
 Cloud Infrastructure as a Service (IaaS)
Rent Processing , Storage, Network Capacity, and other
Fundamental Computing Resources
