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 10/28
