Benefits of Virtualisation |
|
|
Partitioning
- 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
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
Encapsulation
- Complete virtual machine environment is saved as a single file; easy to back up, move and copy
- Standardised virtualised hardware is presented to the application - guaranteeing compatibility
