策略在网络配置中发挥着重要作用，因此在提供安全和高性能服务方面发挥着重要作用，特别是在多租户云数据中心（DC）环境中。与此同时，通过虚拟化进行的弹性资源配置通常会忽略策略需求，假设策略实现由底层网络基础设施处理。这可能导致违反策略、性能下降和安全漏洞。在本文中，我们定义了一个POLicy-Aware和网络感知的VM管理方案，共同考虑通过虚拟机（VM）迁移降低DC通信成本，同时满足网络策略的要求。我们证明了这个问题是NP-难的，并推导出一个有效的近似算法，以减少通信成本，同时坚持政策约束。通过广泛的评估，我们表明，在不同的聚合流量和配置策略，可降低38%的拓扑范围内的通信成本。
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. This can result in policy violations, performance degradation and security vulnerabilities. In this paper, we define PLAN, a PoLicy-Aware and Network-aware VM management scheme to jointly consider DC communication cost reduction through Virtual Machine (VM) migration while meeting network policy requirements. We show that the problem is NP-hard and derive an efficient approximate algorithm to reduce communication cost while adhering to policy constraints. Through extensive evaluation, we show that PLAN can reduce topology-wide communication cost by 38% over diverse aggregate traffic and configuration policies.
