Definition
A Virtual Machine (VM) is an emulation of a computer system that runs on top of another physical system. VMs provide hardware-level isolation and run a full operating system.
Why it matters (in Poovi’s context)
Docker is often presented as a lighter-weight and more efficient alternative to VMs for many use cases, offering similar isolation benefits with less overhead.
