Are enterprises ready to use SDN yet?
Software-defined networking (SDN) gained early traction with the companies that had the resources to deploy it and a clear, immediate need for its benefits: cloud providers, carriers and hyper-scale data center operators. They were eager to use SDN to make their networks more flexible, programmable and scalable. More importantly, they were willing to accept the possible hazards that come along with adopting a radically different network architecture.
It was expected that SDN would soon trickle down to the enterprise. Yet even after several years, it turns out we're still in the early days, and many enterprises are not yet ready (or willing) to use SDN in their networks.
It's time to look at realistic SDN use cases and deployment models for mainstream enterprises -- not just companies like Amazon and Google. In this issue of Network Evolution, learn more about how enterprises are likely to use SDN and if it will ever become the new normal in networking.
Also in this issue, we explore what lessons network engineers can take away from the spate of high-profile network outages that affected companies such as United Airlines and the New York Stock Exchange earlier this year. Learn more about what's likely to take down your network and what steps enterprises can take to avoid it.
Additionally, network engineers weigh in on the growing pressure to improve their fluency in security in light of the ongoing wave of data breaches and how it's affected their jobs.

Software-defined networking isn't just for carriers, cloud providers and hyper-scale Web companies. Instead of asking "Why SDN?", some mainstream enterprises are asking "Why not?"
Downtime is often chalked up to human error. But several high-profile outages this year were blamed on faulty technology. Which is more dangerous to your network?
Network engineers who have focused primarily on honing their routing and switching skills say having limited network security training is no longer adequate.
In this Q&A, a network engineer at the Rochester Institute of Technology explains his favorite weapons against network threats: user education and vulnerability scanning.
