There are a number of possibilities for virtual machines and they are used in a variety of ways. Here, we list the main examples of their practical uses: Run multiple operating systems: the most common use of virtual machines is the ability to run multiple operating systems on a single device. For example, you can have a computer with a Windows operating system and install Linux and macOS in a virtual machine to run programs that are not compatible with Windows, for example. Software development and testing: virtual machines allow more possibilities for developing, testing and debugging applications without impacting the main infrastructure. With a virtual machine, there is the possibility of taking snapshots of the system, easily enabling rollback and controlling different versions of systems for testing in multiple scenarios. Cloud Computing: Many cloud service providers offer virtual machines as part of the frameworks available to users.

Companies and people can manage virtual machines in the cloud, which allows them to scale infrastructure in a cheaper and more practical way compared to spending on physical hardware. Cyberthreat containment: Cybersecurity experts can use Canada Mobile Database virtual machines to examine websites or files potentially infected with malware . Opening malicious files inside a virtual machine prevents the infection from spreading to other virtual machines installed on the same device. Furthermore, it is easy to reset the virtual machine to the stage before the infection, which allows you to take risks in a more controlled way. Virtualization helps protect against online scams and cyber threats.



Fight and identify cybercriminals: cybersecurity researchers use virtual machines to create honeypots, that is, spaces that exist to attract and deceive cybercriminals, all with the aim of identifying them, seeing how they act and adopting security measures. Safe web browsing: with a virtual machine, you can browse more securely. If you receive spam emails, for example, or visit websites that are not secure, you can use a virtual machine to browse with more integrity. If malware is installed on the virtual machine, the threat is contained there and does not spread to the hosting device. Back up existing operating systems: Virtual machines also help you maintain backups of your systems. Run older programs: Older software, in general, suffers from incompatibility with more current operating systems and hardware. With virtual machines, there is the possibility of installing older operating systems and, thus, running these programs with greater compatibility.
