    Why IT Is Investing in Software-Defined Networking

    The emerging area of software-defined wide-area networking allows applications to be delivered efficiently and securely across hybrid networks and hybrid clouds.

The vast majority of IT departments are moving forward with software-defined networking (SDN) initiatives, according to a survey from Riverbed Technology. The accompanying "Software-Defined IT Survey" report indicates that, through SDN, technology professionals are looking to increase the speed of applications and services delivery, while reducing errors and costs. Simply defined, SDN merges the management of network and apps services into centralized software platforms for better provisioning and configuration. And the "next big thing" appears to be software-defined wide-area networking (SD-WAN), which applies SDN to WAN connections, expanding options for device and network configurations over large geographic distances. "With the increasing complexity in today's hybrid IT environments, organizations seek better ways to have full visibility and deliver applications across their distributed enterprise," said Paul O'Farrell, senior vice president and general manager of the SteelHead and SteelFusion business units at Riverbed Technology. "With the rise of SaaS applications, coupled with an insatiable demand for more bandwidth, traditional approaches to wide-area networking no longer meet the needs of business. The emerging area of SD-WAN allows applications to be delivered securely and optimally across hybrid networks and hybrid clouds with reduced cost, increased speed/agility and streamlined management." A total of 260 systems administrators, network architects, information systems managers, systems analysts and other IT professionals took part in the research.
