Hierarchical Queue-Based Task Scheduling
Wanqing You, Kai Qian, and Ying Qian
To better analyze the performance of Cloud Computing provisioning policies as well as resources allocation strategies, a toolkit named CloudSim was proposed. With CloudSim, the Cloud Computing environment can be easily constructed by modeling and simulating cloud computing components, such as datacenter, host, and virtual machine. A good scheduling strategy is the key to achieve load balancing among different machines as well as to improve the utilization of basic resources. Recently, the existing scheduling algorithms may work well in some presumptive cases in a single machine; however they are unable to make the best decision for the unforeseen future.
