垂直剖析監視器與精細資源分配之虛擬化伺服器管理

Abstract

現代小型伺服器與虛擬化技術的普及化，小型私有雲已成為個人或小企業提供網路服務或平行計算資源的有力選擇。小型私有雲受限於有限的硬體資源，與大型雲端環境相比，除了每台伺服器的硬體資源不一致，其不規則的網路拓樸也是一個鮮明的特色。 在虛擬機器的資源管理上，已有許多論文提出基於單台機器的資源監控與分配系統，或基於大型雲端的資源平衡與虛擬機器搬遷，但對於小型伺服器所構成小規模多主機的私有雲環境還沒有太多研究。 本篇研究中我們實作了一個虛擬化伺服器管理系統，透過垂直分析監控來評估虛擬機器中的服務品質，並以此資訊來進行更細緻的資源分配，藉以達到高效能或節能的目的。

With the popularity of microserver and virtualization technology, private cloud has already become a good choice to provide network service or parallel computing power. Compare to public cloud enviroment, ununified hardware resource and irregular network topology is the feature of privte cloud. For virtualized resource management, previous works are mostly focusing on ether the hardware resource monitor and provision based on single host or resource balancing and virtual machine(VM) migration on public cloud, private cloud enviroment is seldom mentioned. In this paper, we implement a virtualized server management system which uses vertical profiling monitor to estimate the Quality of service (QoS) of VM then uses this information providing fine-grained resource provision, finally achieve high performance or power saving management.
