1. virtual objects are a variety of resources
2. Following the logic of virtual resources after the user hides unnecessary details
3. Users can implement some or all of the functionality of its real environment in a virtual environment
2.2 virtualized way
Mainstream virtualization service providers
2.3 common type of Virtualization
(1) server virtualization
A virtual server in a plurality of servers logically isolated from each other and operate independently
(2) network virtualization
Network device N: 1 virtualization technology IRF
You can achieve multiple physical network devices into a single virtual network device
