    IT Reduces Costs

    For starters, enterprises won't need expensive switches to shape network traffic, since admins can do it themselves with automated tools.

    It's Open Source

    Because SND adheres to open standards, it can operate with any vendor's network hardware.

    It's Extremely Agile

    With SDN, users more readily connect to different clouds, apps and network devices.

    It Makes Provisioning Easier

    From the admins' perspective, setting up a network is as simple as creating a virtual machine instance in an SDN environment. As a result, they're more likely to strike the right balance between over-provisioning and service shortfalls.

    It Improves Security

    SDN can virtualize security appliances for better scalability, while centralizing security controls.
 

It's been described as the "new cloud"—not only for its potential impact upon the enterprise, but because there's a general sense of mystery about what exactly it is. In this case, we're talking about software-defined networking (SDN). As defined on a purely technical level, SDN establishes a layer of software between bare network components and the IT admins who configure them, according to Corus360, a Norcross, Ga.-based IT support and professional services firm. This means admins can make network device adjustments through a software interface instead of manually configuring hardware or physically accessing network devices. The upshot: Admins actually shape network traffic, and what once took days to configure is now conducted automatically, in real-time. Yes, like the cloud in the early days, there's still considerable confusion with respect to a precise definition of SDN. Yet, clarity should take hold as CIOs learn more about its benefits and overall adoption grows. To provide a greater awareness of SDN, we're providing the following stats about the emerging technology, as well as its potential enterprise benefits. They were adopted by a number of online resources, including those posted by Corus360 and the Open Data Center Alliance. For more about Corus360's perspective on SDN, click here.
