Virtualisation enables multiple virtual systems on one physical system. For example, on one physical server you could have the following applications running independently and concurrently:

Once the virtual systems are configured they're basically just virtual hard drive and configuration files. This means that you could store a copy and if one physical server went down, it's easy enough to transfer them to another.

Advantages:

• More secure
• Reduced hardware costs
• Shared hardware resources
• Reduced power consumption
• Improve resource utilisation
• Simplify management
• Increased business agility
• Aggregate your workload

Deploy additional servers (new business applications) onto existing physical platforms.
