Will Virtual Technology dominate Linux?

There have been many major events in the IT industry this year, and some may change our lives. What will happen next year? According to speculation, virtual technology may become the future development direction.

Becker said that the Linux cluster system should pay more attention to the development of virtual technology and high feasibility, and explained the reasons in his interview. At the same time, he gave some suggestions to users who switched to Linux cluster Symmetric Multi-processing.

Besides his role in Beowulf, Becker is also the founder and main scientist of Scyld software. He has just joined the expert group on this site and serves as a special expert to answer users' questions about Linux Clusters and servers.

Are there any Latest Developments in Linux cluster technology?

Donald Becker: at present, the hot spot in cluster technology is virtual technology. Two famous traditional virtual technology systems are VMWare and Xen. VMWare imitates and simulates the hardware of a personal computer. This allows it to run almost all operating systems in its own OS.

However, one drawback of the development of virtual technology is that it often implies and relies on some large upper-layer technologies. As a result, VMWare has no chance to optimize the system by imitating some upper-layer technologies. Xen is a system management program that runs multiple operating systems at the same time. It is not a comprehensive imitation, thus reducing the dependence on upper-layer technologies. However, it still needs to optimize its core technologies.

What is the difference between the virtual technology on a Linux cluster and other methods?

Becker: Both VMWare and Xen imagine that they can run and fully Install Multiple kernels. Running clusters provides the opportunity not limited by virtual technology, and creates an easy environment where only the necessary conditions for running applications are met. When the system server has a task that requires the main network terminal to complete, then the computer terminal only needs to run the application, which can improve work efficiency, this is also formally different from the traditional virtual system.

Let's wait and see the future of virtual technology.
