Software-Defined Networking (SDN) is a new architectural approach to designing, building, and managing networks. It separates network services and traffic management from the underlying hardware and allows business applications to program the creation and coordination of network services through a centralised control mechanism.
Business Benefits of Software-Defined Networking
SDN has demonstrated the capacity to turn the network into an enabler of modern IT environments and business needs and not a bottleneck.
SDN offers significant business benefits such as:
- Agility - faster rate of innovation and responsiveness. Exposing the value of rich network analytics for big data applications in your business.
- Network security - improved security, compliance and active defence.
- Automation - enhanced virtualisation, cloud orchestration and optimised network assets.
- Lower OPEX - lower operational and capital expenditure.
