Partitioning: In virtualization, many applications and operating systems (OSes) are supported in a single physical system by partitioning (separating) the available resources.
Isolation: Each virtual machine is isolated from its host physical system and other virtualized machines. Because of this isolation, if one virtual-instance crashes, it doesn’t affect the other virtual machines. In addition, data isn’t shared between one virtual container and another.
Encapsulation: A virtual machine can be represented (and even stored) as a single file, so you can identify it easily based on the service it provides. In essence, the encapsulated process could be a business service. This encapsulated virtual machine can be presented to an application as a complete entity. Therefore, encapsulation can protect each application so that it doesn’t interfere with another application.
APPLICATIONS OF VIRTUALIZATION
Virtualization can be applied broadly to just about everything that you could imagine:
Memory
Networks
Storage
Hardware
Operating systems
Applications

Characteristic of application virtualization
- Allows the running of legacy apps
- Enables cross-platform operations
- Prevents c0nflicts with other virtualized apps
- Permits users to run multiple app i.nstances—if not virtualized, many apps can detect the running of an i.nstance and won't allow new ones.
