The future of Virtualization

"Virtual technology will determine the future of the economy. "--John Chambers, president of Cisco

What is virtualization?

Virtualization represents a huge trend to transform physical resources into logically manageable resources, breaking the barriers between physical structures. In the future, all the resources are transparent to run on a variety of physical platforms, the management of resources will be in a logical manner, fully realize the automatic allocation of resources, and virtualization technology has become our only tool to achieve this ideal.

Virtual server technology is the representative of virtualization technology, it brings people unprecedented experience. What can be done with Virtual server technology, let's take a look at the application of virtualized servers in reality:

Research and development and testing

The first thing people think about the application of a virtualized server is to develop a test environment, because the development and testing staff need to use many different

Operating system environment, if each platform uses a physical server, this will be very difficult to prepare the test environment, a small test changes need to reload several such test server. If a test organization needs hundreds of servers for stress testing, it is almost impossible to prepare a test environment for pure physical servers, and virtualization technology is undoubtedly the best choice. By implementing multiple operating systems on a single physical server, or by implementing hundreds of virtual servers, virtual server technology greatly reduces the cost of development and testing. Fast server Backup/recovery, opening, and reloading provides a perfect test environment for research and development and testers.

Server Merge

Many enterprise users have to face the embarrassment: each implementation of an application to buy a computer, with the application of the increase in general to buy a lot of difficult to change the resources; more and more servers to accomplish different tasks, management becoming more and more complex, and server utilization is very low, only for 15%~20%, Cause a great waste of resources. Therefore, the integration of a variety of different servers are welcomed by the user, but the integration of the server how to allocate resources, and ensure that every application of the normal operation? It is a problem for the server to grow large, and it is also a problem to divide large computational resources into small chunks. The advent of virtual server technology easily solves the problem of server merging, which is favored by more enterprise users.
