virtual network functions (VNF)

Virtual Network Functions (VNFs) are software-based solutions that perform specific networking tasks—like firewalls, load balancers, or routers—without needing dedicated physical hardware. They run on general-purpose servers, enabling flexible, scalable, and cost-effective management of network services. VNFs can be deployed, updated, or moved easily, allowing networks to adapt quickly to changing demands. Essentially, VNFs replace traditional hardware appliances with software running in a virtual environment, streamlining network operations and enabling more dynamic and efficient infrastructure.
