Optimizing HW utilization efficiency by abstracting the hardware layer from the software layer. Provides the runtime environment for the Guest OS and Guest Applications Provides the boot environment for the hypervisor (if bare-metal hypervisor is not used) Responsible for emulating hardware configurations to Guest OS. (Examples: VMware ESXi, Eucalyptus KVM) Guest Application Guest OS Virtual Machine Hypervisor Host OS or Bootstrap Virtualization:
Virtualization is a technique that allows running more than one server (i.e. Virtual Machines) on the same hardware.
