In-Depth Information
The private and public cloud having 20 and 90 heterogeneous type servers are
considered for simulation. Pay-per-use model is used for billing. Few requests are
getting when private cloud is overloaded, we made 50 resource allocation requests at
different time intervals that is-low priority and high priority. Set the time for public
cloud and private cloud to fulfill the request. For Rule Based and Non-Rule Based
approaches we simulated different combinations of priorities among these requests.
Computing resource is more costly than storage resource utilization. We consider only
computing resource utilization. Private cloud utilization is found to be 64% in Non Rule
Based approach and 70.59% for Rule Based approach. Our approach depends on Rule
Based Resource Manager that proves to be cost effective in money spent for using cloud
resource. Our approach considers security requirements of confidential and never
permits to pass the organization's firewall and provide the services in time.
