Infrastructure as a Service (IaaS) is a cloud computing service that allows
businesses to rent or lease servers in the cloud for compute and storage
(avinetwroks.com). Users can run any operating system or application on the
rented servers without incurring the fees of server maintenance and operation
(avinetworks.com).
Providers of public cloud infrastructure-as-a-service (IaaS) establish a common
multi-tenant IT infrastructure by "virtualizing" hardware resources, breaking
hardware into different and independent units for purchase on a pay-per-use basis,

in response to individual customers' needs (Benzina, K).In a private cloud model,
computer resources are allocated for a single organization's exclusive usage,
