A virtual machine (VM)
A virtual machine (VM) is a software-based simulation of a physical computer. It runs an operating system and applications just like a real machine, but it operates in a virtual environment, using resources (CPU, memory, storage, etc.) from a physical host machine. Here are some key points about virtual machines: Isolation: Each VM operates independently from the host and other VMs. It has its own OS, which allows multiple operating systems to run simultaneously on the same physical hardware. Resource Allocation: A VM uses part of the host’s resources, such as CPU, RAM, and storage, which are allocated and managed by the hypervisor (the software that creates and manages VMs). Flexibility: VMs can easily be created, modified, or deleted, making them ideal for testing, development, and running applications in isolated environments without affecting the host system. Backup and Migration: Since VMs are just files, they can be backed up, cloned, or moved to different physical servers easily. Use Cases: VMs are commonly used in cloud computing, server consolidation, software testing, and development environments.
