"Decoupling of Software to Hardware is called NFV"
NFV decouples network functions from dedicated hardware and deploys these network
functions on general-purpose x86 servers, storage, and network devices. On an NFV network,
hardware resources are abstracted into pools and carriers can rapidly roll out services using the
resources from these pools. Additionally, an NFV network allows for elastic scaling and
automated O&M.
In telecom world, this time ETSI rule NFV framework unlike 3GPP.

What is Hypervisor?
Hypervisor is the virtualization software layer between physical servers and operating systems. It takes the role of the virtual machine monitor (VMM) and allows multiple operating systems and applications to share the hardware. Mainstream hypervisors include open-source KVM and Xen, Microsoft HyperV, and VMware ESXi.
