Abstract
With the rapid development of cloud computing, the datacenters are widely used in various areas. Connected by optical fiber, the datacenters are always distributed unbalanced, as the service requirements are very different in different regions. To ensure each datacenter’s stable operation and make them share the equal amounts of risk, the service resources need to be distributed to distinct datacenters proportionately. Considering the service recourses of datacenters, this paper is aimed at proposing a dynamic load balancing algorithm. The algorithm, named Average Variance, can help the new tasks to be distributed with a dynamic adjustment on the basis of the current datacenter’s situation in real-time. And in this way, it can achieve the minimum average variance among datacenter’s occupation of service resource. The simulation results demonstrate that the Average Variance has a better performance than the Round Robin. Furthermore, the main consideration of the node in this paper is the utilization in each CPU.
