So You Have Decided to Adopt SDN… What Now?

Looking to reap benefits like traffic flexibility and self-monitoring capabilities, businesses are increasingly turning to software defined networking (SDN) as an alternative to legacy hardware-based architecture. But if your business recently deployed SDN, you might be wondering exactly how to maximize its effectiveness.

While SDN simplifies some aspects of network management by placing control of various devices in one place, it also creates some issues. For instance, the technology may:

Make application management more difficult because the traffic path is automated

  • Cause troubleshooting to be more challenging because not all network devices are produced by a single vendor
  • Require a significant learning curve for network engineers unfamiliar with the architecture

Network monitoring tools can be a cure for these SDN ills. For instance, real-time performance monitoring helps ensure that even automated applications are running smoothly and alerts network engineers to any potential issues.

Moreover, network flows analysis simulates the effects of possible events to ensure the network is able to handle any sudden changes. Additionally, network forensics help identify security threats and inform network managers of problems before they escalate and result in data breaches.

Like many emerging technologies, SDN offers real promise for organizations that are prepared for implementation. But refusing to adopt SDN in an environment where it makes sense, simply out of fear, is bad business as it may keep your network from operating at its full potential. Network monitoring tools are created to optimize performance; you simply have to let them do their jobs.
