In these cases, a VM can be used to run software designed for a different OS than is native to the host computer. Additionally, certain users may have specific needs that cause them to use different hardware than the rest of the organization, but still need to access company-standard apps. Running software designed for a different OS: Some applications are only available for a specific platform. Users who need to run these applications can run them on an old OS from a VM. Running legacy software: Companies may have custom or specialized applications that can’t be run in a modern OS but must still be used by the business. Performing such tests on VMs is simpler and more cost effective than having to test on several individual physical machines. Any organization that is looking to deploy a critical update may wish to test that update on a VM instance and identify possible incompatibilities before deploying it across their organization. Software, OS, and application testing: While software developers naturally need to test their applications in different environments, they aren’t the only type of company that may need to do so. They basically offer the same experience as a desktop PC but without the hardware maintenance. VMs are also isolated from all other VMs on the network, and they continue to exist on the system even after the user signs off. A greater range of applications are available on VMs as compared to virtual desktops. Virtual machines, on the other hand, offer a customizable virtual PC experience that does provide the user with specific hardware resources. These workstations do not use virtual hardware resources such as CPU, memory, or storage, and they are no longer active when the user logs off. The desktop interface is limited, and users only have access to specific applications. Users can easily access their virtual desktop remotely over the Internet and work on it with a consistent experience regardless of the device they use to access it. This technology creates a virtual workstation that offers a standard, shared experience across all virtual desktops on a central network. Companies may have a mix of these two options in their network, depending on their needs. There are two primary ways that virtualization is used by organizations. For users who have significant performance demands, latency or resource availability issues in a VM environment may make them hesitant to work on a VM. And having a hypervisor layer and multiple OSes running on the same host system does come with a performance cost. The administration and management of a VM environment does require some expertise from IT staff. However, there are some trade-offs to running VMs.
