Network Function Virtualization By Ken Gray and Thomas D. Nadeau
Network Function Virtualization (NFV) represents a transformative approach to designing, deploying, and managing network services. Traditionally, network functions such as firewalls, load balancers, and routers were tightly coupled with proprietary hardware appliances. This hardware-centric model often led to inefficiencies, high costs, and inflexibility in scaling services. NFV disrupts this paradigm by decoupling network functions from…
