Experience: Clearly reflects the effect of server integration

                  For the data center, there is a common problem with server application efficiency. The usual solution is not to buy more servers. The data center needs to increase its flexibility on the basis of having a large number of servers, rather than a never-ending procurement server. Today, this can be done with virtualization technology. When an application sends a request to its server, the IT manager only needs to move the application to another server, regardless of whether it is offline.

effective integration server is an obvious advantage of virtualization technology. With server virtualization technology, a physical server can be partitioned into multiple virtual servers, each running its own operating system and storage space for a dedicated server.

In addition, virtualization technology, the server breaks the one-relationship existing applications and services, in an environment of today's data center, making the original "one application, one server" model of application development Go to 5 to 10 virtual servers running on a single physical server. In this case, the data center can achieve utilization of more than 90%.

However, in essence, virtualization role is to make Caozuojitong and applications from the physical hardware were fixed service applications.

although only 6-8% of the server virtualization technology, but I believe this situation will soon change happen. Industry experts predict that about 90% of servers will be virtualized in the next two years. However, its real purpose is to go beyond the simple integration of servers. For the data center, virtualization technology is only how to effectively apply it. But new virtualization technologies include migration of applications, high-availability fault tolerance, virtual desktops, and cloud computing.
