Energy Consumption Improvement and Cost Saving by Cloud Broker in Cloud Datacenters

Using a single cloud datacenter in Cloud network can have several disadvantages for users, from excess energy consumption to increase dissatisfaction of users of service and price of provided services. The Cloud broker as an intermediary between users and datacenters can play a key role to enhance users' satisfaction and reducing energy consumption of datacenters that are located geographically in different areas. In this paper, we have attempted to provide an algorithm that assigns datacenter to users through rating various datacenters. This algorithm has been simulated by Cloudsim and will result in high levels of user satisfaction, cost-effectiveness and improving energy consumption. In this paper, we show that this algorithm can save 44% of energy consumption and 7% of cost saving to users are in sample simulation space
