1. Virtualization

2. Traditional App/Server
Single OS image per machine
Software and hardware  tightly coupled
Underutilized resources
Inflexible and costly infrastructure

3. Virtualization - Green Focus
The Reality:
Most servers only use 5-15% of their capabilities on average, while consuming 60-90% of their peak power.
The Solution - Virtualization: 
Use one server to host multiple applications.
Reduce energy consumption
Reduce CO2 emissions
Running fewer, highly utilized servers frees up space and power. Less space and power is better for environment and saves money.

4. What is virtualization?
Virtualization allows one computer to do the job of multiple computers.
Virtual environments let one computer host multiple operating systems at the same time

5. Virtual Server Model
Hardware-independence of  operating system and applications
Virtual machines can be provisioned  to any system
Can manage OS and application  as a single unit by encapsulating  them into virtual machines

6. How does it work? Virtualization transforms hardware into software.
It is the creation of a fully functional virtual computer that can run its own applications and operating system.
Creates virtual elements of the CPU, RAM, and hard disk.

7. Virtualization… It is divided into two main categories:
Platform virtualization involves the simulation of virtual machines.
Resource virtualization involves the simulation of combined, fragmented, or simplified resources.

8. Virtualization - Why? Reduce Real Estate Needs Increase Up Time
Reduce CO2 Emissions, Power and Cooling Requirements
Increase Flexibility
Reduce Overall Costs

9. Pros Benefits include freedom in choice of operating system.
It saves time and money.
Consolidates server and infrastructure.
Makes it easier to manage and secure desktop environments.

10. Cons
Only powerful computers can successfully create virtual environment.
Requires training to operate.
