SDN is a new, dynamic network architecture that transforms traditional network backbones into more intelligent service-delivery platforms. IT leaders can use SDN as a tool to change the way they do business. For example, enterprises can foster closer relationships with their customers by offering greater online access to select data over the enterprise network. A financial services firm can give large corporate customers the opportunity for third-party reporting, governance, or even allow analytics firms to directly access enterprise credit card transactions, obviating the need for intermediate sites and cumbersome manual process steps that are needed to provide sufficient multi-level security. An SDN would create virtual network partitions governed by stringent and limited access policies, and security to decrease unauthorized access.
