What are the advantages of virtualized data centers compared with traditional data centers?

Advantages of virtualization technology:

(1) Higher resource utilization-Virtualization can support the dynamic sharing of physical resources and resource pools, and improve resource utilization, especially for different loads whose average demand is far lower than the demand for dedicated resources.

(2) Reduce management costs-Virtual can improve employees' work efficiency through the following ways: reducing the number of physical resources that must be managed; Part of the complexity of physical resources is hidden; Simplify the task of public management by realizing automation, obtaining better information and realizing central management; Realize automation of load management. In addition, virtualization can support the use of common tools on multiple platforms.

③ Improve the flexibility of use-through virtualization, resources can be dynamically deployed and reconfigured to meet the ever-changing business needs.

(4) Improve security-Virtualization can achieve isolation and division that a simple * * * sharing mechanism cannot achieve, and these characteristics can achieve controllable and secure access to data and services.

⑤ Higher availability-Virtual can delete, upgrade or change physical resources without affecting users.

⑥ Higher scalability-According to different products, resource division and aggregation can support the realization of virtual resources much smaller or larger than a single physical resource, which means that you can adjust the scale without changing the configuration of physical resources.

⑦ Interoperability and investment protection-Virtual resources can provide compatibility of various interfaces and protocols that the underlying physical resources cannot provide.

⑧ Improve resource supply-Virtual can allocate resources in smaller units compared with a single physical resource unit.
