1. Virtualization OVERVIEW
2007 Baptist State Technology Group

2. Intro to Virtualization
Separates the physical hardware from the operating system.
Allows multiple virtual machines, with heterogeneous operation systems to run in isolation, side-by-side on the same physical machine.
Each virtual machine has its own set of virtual hardware (e.g. RAM, CPU, NIC, etc.) upon which an operating system and applications are loaded.

4. Intro to Virtualization
Virtual machines are encapsulated into files, making it possible to rapidly save, copy and provision a virtual machine.
Full systems can be moved, within seconds, from one physical server to another for zero-downtime maintenance.

5. Benefits of Virtualization
Partioning
Multiple applications and operating systems can be supported within a single physical system
Servers can be consolidated into virtual machines on either a scale-up or scale-out architecture
Computing resources are treated as a uniform pool to be allocated to virtual machines in a controlled manner

6. Benefits of Virtualization
Isolation
Virtual machines are completely isolated from the host machine and other virtual machines. If a virtual machine crashes, all others are unaffected
Data does not leak across virtual machines and applications can only communicate over configured network connections

7. Benefits of Virtualization
Encapsulation
Complete virtual machine environment is saved as a single file; easy to back up, move and copy
Standardized virtualized hardware is presented to the application – guaranteeing compatibility

8. Why Virtualize? Consolidate Servers & Increase Operational Efficiency
Minimize Downtime & Ensure Business Continuity
Streamline Software Development and Testing

9. Why not Virtualize?
Hardward for servers is limited to CPU, memory, NICs, hard drives, cd/dvd, video, partial USB, partial SCSI.
Hardware for workstations is limited to above plus audio, full USB support.
Add-on hardware such as fax cards, voice-cards, etc, do not work.
