Towards Proactive Resource Management in Virtualized Datacenters

Proactive resource management involves taking actions to make resources available for upcoming load spikes. Proactive resource management is highly desirable for managing resources in a multitenant cloud where it is common to have hot-spots at some locations, while still having spare resources scattered throughout the datacenter. Inability to quickly use fragmented spare resources in a datacenter during load spikes causes administrators to do host-level over-provisioning. Running hosts at low utilization leads to lower consolidation ratios directly impacting the bottom-line. In this paper, the authors present key challenges in doing proactive resource management in virtualized environments.
