Network Function Virtualisation (NFV) What is Network Function Virtualisation (NFV)? Network Function Virtualisation (NFV) is a technology that replaces traditional network hardware with virtualised software functions, improving scalability and reducing costs. Explanation NFV enables functions like firewalls, load balancers, and routers to run on standard servers, rather than dedicated hardware. This approach streamlines deployment and maintenance in modern networks. Practical Example of NFV A telecom provider uses NFV to virtualise its firewall and routing functions, reducing hardware dependency and enabling faster upgrades.
