What is NFV?

Definition: Network Function Virtualization, or NFV, is way to reduce cost and accelerate service deployment for network operators by decoupling functions like a firewall or encryption from dedicated hardware and moving them to virtual servers.

Instead of installing expensive proprietary hardware, service providers can purchase inexpensive switches, storage and servers to run virtual machines that perform network functions. This collapses multiple functions into a single physical server, reducing costs and minimizing truck rolls.

If a customer wants to add a new network function, the service provider can simply spin up a new virtual machine to perform that function.
