Ringkasan	Network Function Virtualization (NFV) is a paradigm that implements traditional network functions (firewalls, load balancers, gateways, packet inspection) as software running on commodity servers instead of proprietary hardware appliances. Introduced by ETSI (2012), NFV reduces capital and operational expenses by leveraging cloud infrastructure and enabling rapid deployment of network services. Combined with SDN, NFV enables on-demand service creation and network slicing. It is now central to 5G and cloud-native network architecture.	Software-Defined Networking (SDN) is a network architecture paradigm that decouples the control plane (routing decisions) from the data plane (packet forwarding). Introduced by McKeown et al. (2008) with OpenFlow, SDN enables network programmability by centralizing control logic in software-based controllers that direct forwarding behavior of simple programmable switches. SDN has transformed network operations, enabling rapid service deployment, traffic engineering, and cloud integration. It is now foundational in data centers and service provider networks.
