Software-defined networking: Flexibility, automation, and cost-efficiency

Software defined networking is transforming IT architecture and operations. Learn about potential benefits and considerations for transition to SDN.

For the era of the cloud

Imagine if you had the ability to centrally manage all your organization’s networking resources. You could quickly and automatically shift them as needed from one application to another. You could draw first on one piece of hardware, then another, then the cloud, then back to your hardware again, depending on what’s most suitable and cost-efficient at a given moment. 

With such a system, you could react quickly to applications’ changing needs, to new business opportunities, or to security breaches. You could find efficiencies and automate many functions. And your network services would no longer be dependent on a particular piece of hardware—or a particular hardware vendor. 

This system could cut your organization’s networking costs, improve the user experience, allow you to use old hardware resources for new challenges, and align your networks with the speed and flexibility that cloud computing, digital labor, and mobile computing demand.  

Such is the promise of software-defined networking (SDN). SDN is a new paradigm, and has begun to redefine both data centers and wide area networks.
