The concept of "virtualization", oddly enough, appeared half a century ago and used specialists at IBM. Currently, virtualization technology is effectively used by large companies to optimize information processes. Virtualization software can speed up and systematize the processes of performance equipment: servers, stations, hardware, applications, personal computers and so on. Systems Virtualization can be divided into the following types: application virtualization. This process allows you to emulate OS resources. For example, if one machine is running Windows, the Windows virtualization or virtualization of Windows 7 in this context will be used in the OS (on one computer) are somewhat inconsistent inconsistent applications.
Moreover, these applications through virtualization can be used simultaneously, without making any changes in the OS, running them with shared server, that delivers the maximum convenience to the user. Provisioning software applications virtaulizatsii company does Microsoft. Presentation virtualization. If you turn virtualization concepts, then start emulating the user interface. For example, if a user works with a specific application, this application will run on a remote server, and it will be transferred to a picture of the application. This kind of virtualization decide based on products from Citrix and Microsoft. Server virtualization.
Extremely handy thing allows you to run from one physical server more virtual. Virtual server is, in turn, will emulate the structure and operation of physical server. The software and custom applications to use server virtualization VmWare Virtualization, as well as the products of Microsoft. The company VMware Workstation, incidentally, proved to be a good idea on the market of virtual machines. OS-level virtualization. The main task of this type of virtualization Virtualization CPU (1 core OS), allowing it to locate and isolate the part of running services. It is realized based on products from SWsoft. Virtualization as a whole has several advantages such as reduced hardware costs, lower costs software, maintenance, finally, electricity, generally increasing the efficiency of the equipment. Hardware virtualization in general, would save both money and time. After all, she conceived and developers for these purposes.
