Network Traffic-Aware Virtual Machine Placement with Availability Guarantees Based on Shadows

Virtual Machine Placement (VMP) is critical for resource management in data centers. Network traffic and availability of VMs are key factors should be considered in VMP. The Shadow-Based Solution (SBS) guarantees the high-availability goals of VMP. However, the resource constraints of SBS are not applicable to network capacity. To solve this problem, we proposed a shadow-based VMP model with network traffic constraints for both real and shadow VMs. The experimental results show that the proposed model is more feasible than the original SBS model.
