Virtualization is vital for many information technology (IT) data facilities to create a beneficial computing environment. This process introduces a virtual instance that emulates the real hardware and makes it possible to run similar operating systems (OSs) (Tomsho, 2016). Today, many organizations use this type of technology because of its flexibility, agility, and workload mobility. Additional reasons for virtualization’s popularity are related to its hosted and bare-metal characteristics (Tomsho, 2016). For example, the users of hosted virtualization products may easily support several OSs simultaneously, following a few requirements. Bare-metal virtualization products are usually not cheap, but data centers with solid IT departments implement them. It does not take much time to recover from a disaster with such systems because virtualization stores server snapshots for reversion. Its usefulness is also related to shared storage and combined resources, which reduces prices and offers new options automatically.
In addition to the vivid benefits of virtualization, sometimes, this process is not the best answer to technological problems and computing environments. Some programs are not free, and people need to spend much time and money installing the necessary software and starting to work (Tomsho, 2016). However, the list of situations when virtualization is no longer useful may be expanded. For example, some organizations cannot buy application licenses and run a program legally. There are cases when high-speed interconnects are obligatory for work with hardware and graphics apps. Still, when no dongles are available, it is challenging to complete an operation. Finally, organizations with a limited capacity will not benefit from OS virtualization because of evident differences between physical and virtual machines. However, attention to technological improvements has been paid, and positive changes cannot be ignored, removing problems and offering effective alternatives.
