Choosing to move to the cloud is a complex process, and many decisions must be made before completing the migration. This paper identifies key criteria for a company moving to the cloud and offers a model for determining one of the decisions: which cloud service strategy (Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS)) should be used for a particular cloud migration project. This paper describes these types of services as well as presents a Hierarchical Decision Model (HDM) structure for choosing a service strategy.
