Policy-Aware Virtual Machine Management in Data Center Networks

Abstract

Policies play an important role in network configuration and, therefore, in offering secure and high performance services, especially over multi-tenant Cloud Data Center (DC) environments. At the same time, elastic resource provisioning through virtualization often disregards policy requirements, assuming that the policy implementation is handled by the underlying network infrastructure. In this paper, we define PLAN, a Policy-Aware virtual machine management scheme to jointly consider DC communication cost reduction through Virtual Machine (VM) migration while meeting network policy requirements.
