What is virtual migration?
virtual machines have existed since the 1960s, but have seen only widespread since the late 90s. The virtual machine is a replica of the original physical machine and there may be more virtual machines on a single physical computer. The software emulates all parts of the machine, including hardware and input/output controls (I/O). Using virtual migration, the entire computer system can be migrated into new hardware without any software changes required. This significantly simplifies the upgrades of the operating system (OS) and recovery after the disaster and also reduces the cost of operating technology for the company. Drivers for I/O devices may be incompatible, older programs may not run in a new operation or there may be applications conflicts. Practically system migration can enable support employees to make full testing and tuning of a new operating system before starting.
Financial programs, databases or customer services on the same computer can be risky. When a progress crashes on a computerAM, any further triggering of the application can be negatively affected. If one physical machine is used to host multiple applications, the program can be a disaster program. Practically, the migration of each critical program on its own virtual machine is to restore the crash question of restarting a single virtual system, while other applications leave untouched and lowered.
Software developers can test the application on multiple operating systems on the same physical computer. Virtual computers with Windows®, Linux and Macintosh® operating systems can be set on a single physical computer. Using virtual migration, software can be tested on each platform. Tuning is simplified because every virtual operating system can be restarted or improved without affecting any other platforms.
virtual migration can be used to set old older software on new systems. BusinessesThey might want to keep an old but stable system, but they might want to run it on a new hardware. Virtual migration can allow you to move the entire software system to the new hardware section because virtual systems are hardware independent. The new operating system can be used to host an older system on a virtual computer.
operating costs are reduced by virtual migration. Businesses can buy fewer high -performance servers, while practically hosting more than one fully independent application on each. This allows you to maintain a database or update applications without disturbing other critical missions. With fewer physical systems, fewer hardware support employees are required.
Restoration after a disaster can be simplified by virtual migration and can be as simple as starting the software program. It does not matter whether the hardware is different in the recovery system. All hardware configurations, firmware, axes and applications are virtualizovOna, so on any physical computer you can set a fully mirror system.
