Applications
Operating System
Hardware
So virtualisation uses clever tricks to stretch the same resources to run virtual machines… OS OS

But using ‘virtual’ servers
Virtual
Less physical servers
Better for hosting company
Physical

13. Virtualisation Storage Users get ‘simple’ storage Client
eg all files in ‘one’ place
But using ‘virtual’ storage
Virtual
Multiple physical devices
Linked as ‘storage network’
Physical
Security, upgrades, backups
