As businesses turn to digital transformation to compete, the importance of the network is further amplified due to the ability to tap into multiple resources, as well as the greater assurance gained from faster, reliable networks. Specifically, software-defined networking (SDN) technology now makes it possible to rapidly provision and modify network configurations from an accessible web interface.
Implemented properly, an SDN abstracts the inherent bottlenecks stemming from the limitations of physical cables. While the underlying infrastructure is still required, the virtualisation of multiple cables into a virtual conduit offers much greater flexibility akin to how server virtualisation facilitates the seamless migration of workloads between physical servers.
SDN is ideal for addressing modern enterprise realities, which requires agility in IT to support rapidly evolving business functions. This gives businesses the ability to rapidly scale bandwidth during expansion phases, or to throttle it down during lull periods. This also increases speed to market, as business units tap into self-service capabilities to roll out new service offerings in days rather than weeks or months.
Elsewhere, organisations looking to the cloud to support their IT needs can also leverage new network offerings – powered by SDN, for private, preferential connectivity to the top public clouds. This gives businesses the assurance that performance issues or intermittent data errors will not result in hard-to-detect problems or even trigger a cascade of failures.
