Deployment models and service models

When assessing the separation measures of a given cloud service, there are two factors determining your security and assurance requirements: The deployment model and the service model.


We have isolated three deployment models: public cloud, community cloud and private cloud deployments.


And three service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service(SaaS).
