er, and can be used together giving greater mutual benefits. Many use cases of SDN overlap with those of NFV. Network Functions Virtualization goals can be achieved using non-SDN concept, relying on the techniques currently in use in many datacenters. But using SDN approaches i.e., separation of data plane and forwarding plane can enhance performance, simplify compatibility with the existing deployments, and facilitates operation and maintenance procedures. NFV can support SDN by providing the infrastructure upon which the SDN software runs. The objectives of both the concepts align closely with each other to use commodity servers and switches.

Although the concept of virtualization worked well in the past, there was reliance on the proprietary hardware and slow development pace, which led to long product cycles. The rise of significant competition in communication services from fast-moving organizations operating at large scale has accelerated the growth and momentum across the industry.

Virtualization also helps self-managed redundancy and failover scenarios. Using high autom
