adaptive virtual resource management with fuzzy model predictive control
Resource management in virtualized systems remains a key challenge where the applications have dynamically changing workloads and the virtual machines (VMs) compete for the shared resources in a convolved manner. To address this challenge, this paper proposes a new resource management approach based on Fuzzy Model Predictive Control (FMPC) which can effectively capture the nonlinear behaviors in VM resource usages through fuzzy modeling and quickly adapt to the changes in the virtualized system through predictive control. This approach is capable of optimizing the VM-to-resource allocations according to high-level service differentiation or revenue maximization objectives. A prototype of this approach was implemented for Xen-based VM systems and evaluated using a typical online transaction benchmark (RUBiS). The results demonstrate that the proposed approach can efficiently allocate CPU resource to multiple VMs to achieve application- or system-level performance objective.
