2. Objectives of Virtualization
Enterprise IT World
Make Use of Idle CPU Cycles
Leverage Hardware to Fullest Potential
Saves Power Consumption and Real Estate
Reduced Administration Cost
Faster Deployment of Additional Resources
Effective ROI
Educational World
Provide A Live Environment for Experimentation
Reduced Infrastructure Investment
“Doing More With Less”

3. Current State of Virtualization
Virtualization is Mature And Ready For Prime Time
Enterprise Data Center Deployments
Laboratory and Experimental Projects
Emulate Sizable Network Configurations

17. In Conclusion We Can Do Some Much More With Virtual Networks
Perhaps Need To Form A Study/Advisory Group
Formulate Implementation/Use Guidelines
Formulate Interoperability Guidelines
Shared Virtual Networks Across Institutions
Formulate Plans to Leverage Existing Resources
Avoid Duplication
Consider Security – Exploits Against VMs
Publish Secure Implementation Guidelines
Provide Subject Matter Experts and Technical Advise
Vehicle for Implementation
Perhaps ICT/MPICT
