What are the advantages of virtualization architecture over traditional it architecture?

This is really a lot. Let's start with a few simple and important ones. You can't copy them manually:

1, even if you use 1 to 5, then you can save at least 4 times the physical space and save a lot of electricity.

2. Respond to the business department, complete a system in a few minutes, and think about what efficiency.

3, convenient management, a graphical interface, all systems are fully managed, and there is no need to run the computer room every day.

4, make full use of resources, think about the previous physical machine, how low the resource utilization rate is.

5. Save money (not necessarily if you use a high-profile storage network server, but this is not the most important)

Personally, I think these points are more important, please refer to them.
