Virtual machines are commonly used for a variety of purposes, including:
1. Server consolidation: By running multiple virtual machines on a single physical server, organizations can maximize their hardware resources and reduce costs.
2. Development and testing: Developers can use virtual machines to test software on different operating systems without the need for multiple physical machines.
3. Security: Virtual machines provide a secure sandbox environment for running potentially risky applications or browsing the internet without risking the host system.
4. Disaster recovery: Virtual machines can be easily backed up and restored, making them an ideal solution for disaster recovery plans.
Popular virtual machine software includes VMware, VirtualBox, and Hyper-V. These platforms allow users to create, manage, and run virtual machines on their host systems.
