INFRASTRUCTURE

Virtualization

Abstracting compute, storage, or network resources so that multiple workloads can run on shared physical hardware, with each workload behaving as if it owned the underlying device.

IN PRACTICE

VMware ESXi, Microsoft Hyper-V, and KVM run multiple virtual machines on a single physical server. Network virtualization technologies like VXLAN and NSX do the same for switches and routers, decoupling the logical network from the physical underlay.
