Because Utica College and Ryerson University have the ability to apply cloud economics to applications and this optimize and boost the cost efficiency of IT service delivery.

6. Describe the following types of Cloud services:

SaaS : Software as service is a software distrivution model in which applications are hosted by a vendor or service provider and made available to customers over a network

PaaS: Platform as a service is a cloud computing model that delivers applications over the internet. A cloud provider delivers hadrware and software tools usually those needed for aplication development

IaaS : Infrastrucutre as a service is a form of cloud computing that provides virtulized computing resources over the internet
