Cloud computing reference model: The modelling of service availability based on application profile and resource allocation

Under unconsolidated resources, cloud computing providers have to allocate some resources to fullfil client request based on the on-demand mode. Using the applications profile, Infrastructure-as-a-Service model can be developed. Basically, Infrastructure-as-a-Service model provides resources in the form of computation power (CPU-hours unit), storage (gigabytes unit), network bandwidth (Internet data transfer, GB per day unit), and electrical power (kWh). From service availability point of view, reference model is previously developed as a backup framework. In this research, the development of cloud computing reference model for on-demand services is based on both application characteristics and resources availability. The objective of development model in this research is to decrease idle resources.
