Introduction

• Virtualization is the abstraction of computer
  resources
• That is offering services that rely on mechanisms
  that are not physically implemented on the machine

3
Introduction - Examples

• Remote Services

• Virtual Servers

4
Introduction - Examples

• Virtual Machines

• Hardware Emulation

Background

• 1964 - IBM's Cambridge Scientific Center
  developed CP-40, intended to implement full
  virtualization.
• 1970 - IBM System/370 announced, without virtual
  memory.
• 1972 - Announcement of virtual memory added to
  System/370 series.
• 1997 - First version of Virtual PC for Macintosh
  platform was released.
• 1999 - VMware introduced VMware Virtual Platform.
• 2003 - Microsoft acquired virtualization
  technologies.
• 2005 - VMware releases VMWare Player, a free
  player for virtual machines, to the masses.
• 2008 - In April, VMWare releases VMWare
  Workstation 6.5 beta, the first program for
  Windows and Linux to enable DirectX 9 accelerated
  graphics on Windows XP.

Benefits

• Offload work and provide from the local station
  and provide a desktop environment to users
  remotely.
• An ageing notebook computer can be used simply as
  display and keyboard/mouse device, connecting to
  a remote session running on a server.
• Server consolidation.
• Allows several operating systems to run
  simultaneously on one local desktop machine.
• Stream applications or operating systems out from
  local terminals to office computers.
• Simplifies the use and deployment of many
  graphics intensive applications.
• Management of applications, including control
  over their resource usage and relative isolation.

7
Criticisms

• Virtualization present security risks for
  software.
• Potential performance hits between guest machine
  hardware
• The interception and simulation of privileged
  operations.
• With partial virtualization systems, there is a
  lack of backward compatibility and portability.

8
Should I Use Virtualization?

• Ease
• Simplicity
• Productivity
• Variation
• Effective
• Virtualization is a great tool that benefits many
  people.
