Common virtualization technologies

What are the virtualization technologies

1, CPU virtualization

Virtualization in computer terms usually means that the computing components run on a virtual basis rather than a real one. Virtualization technology expands the capacity of hardware and simplifies the process of reconfiguring software. Simply put, CPU virtualization technology is a single-CPU simulation of multiple-CPU parallelism, allowing a platform to run multiple operating systems at the same time, and applications can all be run in a mutually independent space without affecting each other, thus significantly improving the efficiency of the computer.

2, network virtualization

Network virtualization is currently the industry on the virtualization segmentation of the most ill-defined, there are more controversial concept. In Microsoft's eyes, "network virtualization" refers to a virtual private network (VPN), which abstracts the concept of network connectivity and allows remote users to access an organization's internal network as if they were physically connected to it. Network virtualization can help protect IT environments from threats from the Internet while enabling users to access applications and data quickly and securely.

3. Server virtualization

Unlike network virtualization, server virtualization is the earliest sub-segment of virtualization technology. According to a February 2006 ForresterResearch survey, worldwide awareness of server virtualization among enterprises reached 75%. One-third of enterprises are already using or preparing to deploy server virtualization. This technology, which originated in the 1960s, is increasingly showing its value. Because server virtualization has been in development for so long and is so widely used, many times people almost equate server virtualization with virtualization.

4, storage virtualization

With the continuous operation and development of the information business, storage system network platform has become a core platform, a large number of high-value data accumulated around the application of these data on the platform requirements are also increasingly high, not only in the storage capacity, but also includes data access performance, data transmission performance, data management capabilities, storage scalability and so on. Multiple aspects. It can be said that the advantages and disadvantages of the comprehensive performance of the storage network platform will directly affect the normal operation of the entire system. Because of this reason, virtualization technology another sub-field - virtual storage technology, came into being.

5, application virtualization

The previous several virtualization technologies, mainly focusing on the virtual allocation of resources to optimize the hardware platform, with the increasingly wide range of IT applications, application virtualization as a virtualization family of tomorrow's star on the stage of history. 2006 July by the Forrester Consulting in the United States of America on a variety of different industries, senior IT managers. A July 2006 study by Forrester Consulting in the U.S. of top IT executives across a wide range of industries showed that today's organizations are now treating application virtualization as a business imperative rather than an IT decision. According to statistics, at least 180,000 organizations around the world are now leveraging application virtualization technologies to centralize IT management, enhance security, and reduce overall costs.
