SDN—A Powerful Technology on the Rise
First in a two-part series
Software Defined Networking (SDN) promises to transform enterprise networks into modular, scalable assets that can be assembled and rearranged as business needs require. SDN makes networks just as programmable as the components connected to them.
A survey conducted by investment bank Piper Jaffray found that nearly half of CIOs said they’re either evaluating SDN or plan to use some variation of the technology this year. SDN, concludes Piper Jaffray in its survey report, “is real and here to stay.”
No surprise that in a recent survey conducted by market researcher Infonetics, 45 percent of medium and large North American enterprises now evaluating SDN intend to have the technology live in some fashion this year. And more than 85 percent said they expect to have the technology live by 2016.
For organizations implementing virtualized, complex, mission-critical applications and big data analytics— in other words, just about everyone — that’s powerful. Most corporate networks simply can’t handle the kinds of performance, growth, change management and automation that these advanced technologies demand. SDN is a key enabler on all of these fronts.
SDN achieves these goals by dramatically transforming the way networks are designed, built and run. Consider:
- Where legacy networks are technology-centric, SDN focuses on business drivers.
- Where legacy networks rely on specialized hardware and software funded as capital expenses, SDN can be implemented in software that runs in the cloud and accounted for as an operating expense.
- Where legacy networks are rigid and difficult to re-architect, SDN is software-driven and can be infinitely customizable to changing application performance needs.
The second part in our series will explore the integration, cost and security issues associated with implementing an SDN strategy for the enterprise.
