Fuzzy Modeling Based Resource Management for Virtualized Database Systems

The hosting of databases on Virtual Machines (VMs) has great potential to improve the efficiency of resource utilization and the ease of deployment of database systems. This paper considers the problem of on-demand allocation of resources to a VM running a database serving dynamic and complex query workloads while meeting QoS (Quality of Service) requirements. An autonomic resource-management approach is proposed to address this problem. It uses adaptive fuzzy modeling to capture the behavior of a VM hosting a database with dynamically changing workloads and to predict its multi-type resource needs. A prototype of the proposed approach is implemented on Xen-based VMs and evaluated using workloads based on TPC-H and RUBiS.
