The computer resources referred to here include computing control resources provided by the CPU, data storage resources provided by the hard disk, network transmission resources provided by the network card, etc.
Advantages of Virtualization
(1) The resources are over-sized, such as 128G of physical memory, and 200G of memory can be allocated to the virtual machine. It is generally used in test environments and generally in production environments. Not recommended.
(2) Reduce capital costs and operation and maintenance costs
(3) Minimize or eliminate downtime
(4) Improve the efficiency, effectiveness and agility of the IT department stability and responsiveness
(5) Accelerate the deployment of applications and resources
(6) Improve business continuity and disaster recovery capabilities
(7) Simplify data center management
(8) Availability of real Software-Defined Data Center
(9) Reduce port conflicts
