The Uncertainty Property on Intelligent Resource Provision in Complex Cloud Environment

Resource provision is one of the key issues for multiple objective optimizations in cloud data center. This paper emphasizes the fluctuation of workload and investigates the uncertainty property in complex cloud environment especially in software-defined cloud. By leveraging the uncertainty theory, the resource demand value from workload in each dimension is defined as uncertain variable while the uncertain distribution is applied to quantify the variable. The experimental simulation in this paper shows that the uncertain property has great potential in the combinational resource provision.
