چکیده (انگلیسی):

Cloud has emerged into another enhancement that manipulates the diversity of resources in order to expand
the ability of Cloud facility. Cloud is no longer being seen as one-type service provider. The advantages of
the heterogeneous Cloud give great benefits to the users and have business potential in service market. To
cope with the dynamic nature of heterogeneous Cloud, the Cloud provider needs to have strategies to
efficiently allocate tasks to the resources. Also, to charge the services is another challenge to the Cloud
provider as the resources in the Cloud system are heterogeneous. In this study, we suggest the
implementation of a. Multi-level priority-based scheduling and dynamic pricing into the heterogeneous
Cloud model. We perform an extensive performance evaluation on the model through simulations. We
define the attribute of the Cloud simulation as dynamic and random to address the heterogeneous feature of
the Cloud. Our simulation result shows that the multi-level priority-based is significantly increasing the
resource utilization rate and its integration with the dynamic pricing successfully improves the performance
of the Cloud service in term of satisfaction rate.
