1. Application value of Virtualization Technology

There are many business systems and more and more hardware devices such as servers, but there are not many technical personnel. At the same time, they are faced with the following four situations:

1) waste of resources: the utilization rate of system resources is not high, some servers are idle for a long time, and some servers are overloaded.

2) it is difficult to manage: there are a large number of devices such as servers, routes, firewalls and so on.

3) repetitive work: frequent reinstallation, rework of the system, adjustment of network equipment, etc.

4) tedious parameter configuration: tedious processes such as adjusting CPU memory and hard disk size of a single server.

two。 What is Virtualization?

1) Virtualization means to virtualize a computer into multiple logic computers through virtual technology, and run multiple logic computers on one computer at the same time, each of which can run a different operating system. And applications can run in independent spaces without affecting each other, thus significantly improving the work efficiency of the computer.

2) Virtualization uses software to redefine the division of IT resources, which can realize the dynamic allocation, flexible scheduling and cross-domain sharing of IT resources, improve the utilization of IT resources, and make IT resources truly become a social infrastructure to serve the flexible application needs of various industries.

3. Virtual implementation process

4. Characteristics of virtualization technology

1) High utilization: after the scattered and independent server resources are integrated into a virtual resource pool, the resource utilization is greatly improved.

2) Free configuration: within the resource pool, you can add virtual machines and change virtual machine memory, storage space and other parameters.

3) Unified management: through the virtualization platform, you can clearly view the server operation, hardware health and other information.

4) more stable: through the technical means of virtualization technology, improve the stability of the system and ensure data security.
