Virtual Machines

  • System Virtual Machines allow you to act as if a single physical machine is multiple smaller ones
  • Virtual machines can be created, destroyed, and reconfigured very quickly
  • Individual VMs are isolated from each other and host
  • You can run Windows inside Linux, Linux in Windows, or many more exotic setups
  • The earliest unit of cloud computing was the VM
  • Rent a VM by the hour (or second these days)
