1. The vMatrix: Teleporting Servers via Virtual Machine Monitors (work in progress – LISA’02) Amr A. Awadallah Mendel Rosenblum {aaa,mendel}@cs.stanford.edu http://www.thevmatrix.com Stanford University – Computer Systems Lab – LISA 2002

2. What is The vMatrix?

3. Stanford University – Computer Systems Lab – LISA 2002 Virtual Machine Monitors Virtual Machine Monitor Real Machine (CPU, Memory, Disks, Network) Virtual Machine 1: vCPU, vMem, vDisk, vNet OS1: Windows 2000 Virtual Machine 2: vCPU, vMem, vDisk, vNet OS2: Linux MySQL, Apache Oracle, IIS

4. Stanford University – Computer Systems Lab – LISA 2002 The vMatrix! A network for delivering virtual machines (VMs) between real machines (RMs) running the virtual machine monitor (VMM) software.

5. Stanford University – Computer Systems Lab – LISA 2002 Distinguishing Advantage Backward Compatibility Disadvantage VM files are very large (order of gigabytes)!

6. Stanford University – Computer Systems Lab – LISA 2002 Applications 1.Dynamic Content Distribution Optimal Server Positioning (online games) 2.Server Switching (ala packet Switching) 3.Warm Standbys

7. Stanford University – Computer Systems Lab – LISA 2002 Before: Static Mirroring

8. Stanford University – Computer Systems Lab – LISA 2002 After: Dynamic Distribution

9. Stanford University – Computer Systems Lab – LISA 2002 Complexity: Multi Tier
