出版日期: 2012年12月20日 內容資訊: 英文
簡介

伺服器虛擬化在企業市場中由VMware獨佔,市場滲透率為50%。

本報告提供伺服器虛擬化市場相關調查,VMware和Microsoft的經營管理策略,作為VMware最先進的的虛擬機管理器(Hypervisor)的理由,不同地區的伺服器虛擬化引進情形,及伺服器虛擬化的引進理由等分析,為您概述為以下內容。

摘要

伺服器虛擬化成熟技術

  • 伺服器虛擬化x86市場上優勢技術
  • 伺服器虛擬化的促進因素複雜且多樣

VMware依然是技術最先進的虛擬機管理器(Hypervisor)堆疊解決方案,但Microsoft將追趕上

  • 基本的虛擬機管理器(Hypervisor)比較:尺寸重要
  • 資源經營管理的差異透露虛擬機管理器(Hypervisor)的限制
  • 記憶體經營管理中VMware使VMware密度增加
  • 儲存是Microsoft縮小差距的領域
  • 網路容量成為可用性·性能的關鍵
  • 功能比較概要

經營管理哲學VMware和Microsoft不同

  • VMware投入再定義作業系統所扮演的角色的資訊科技堆疊
  • Microsoft超越只有Windows經營管理

因為混合雲端成為最適合的雲端,服務供應商對市場帶來很大的影響

  • VMware壟斷私人雲端,但混合雲端具有前景

超越2大供應商,提供核心技術為開放原始碼的影響

  • Red Hat Enterprise Virtualization (RHEV) 是虛擬化市場上的黑馬
  • Citrix XenServer 具有企業資質,需要確實維持與對手的平衡

建議

  • 企業
  • 供應商

  • Key messages

SERVER VIRTUALIZATION HAS BECOME A MATURE TECHNOLOGY

  • Server virtualization has become the dominant technology in the x86 market
  • The drivers for server virtualization are complex and diverse

VMWARE REMAINS TECHNICALLY THE MOST ADVANCED HYPERVISOR STACK SOLUTION, BUT MICROSOFT IS CATCHING UP

  • Basic hypervisor comparison: size does matter
  • Resource-management differences highlight the limitations of Hyper-V
  • Memory management enables VMware to increase VM density
    • Page-sharing
    • Ballooning
    • Memory compression
    • Swap to host cache
    • Regular host-based swapping
  • Storage is another area where Microsoft has closed the gap
  • Network capabilities are key to availability and performance
  • Overview of feature comparison

THE MANAGEMENT PHILOSOPHY DIFFERS BETWEEN VMWARE AND MICROSOFT

  • VMware introduced the IT stack that redefines the role of the operating system
  • Microsoft moves beyond only Windows management

SERVICE PROVIDERS COULD SIGNIFICANTLY INFLUENCE THE MARKET AS THE HYBRID CLOUD LOOKS SET TO BECOME THE CLOUD OF CHOICE

  • VMware dominates the private cloud, but the hybrid cloud represents the future

BEYOND THE LEADING TWO VENDORS IT IS THE OPEN SOURCE INFLUENCE THAT PROVIDES THE CORE TECHNOLOGY

  • Red Hat Enterprise Virtualization (RHEV) is the dark horse in the virtualization market
  • Citrix XenServer has enterprise credentials but it needs to ensure it maintains parity with its rivals

RECOMMENDATIONS

  • Recommendations for enterprises
  • Recommendations for vendors
  • Alternative views
