3 Challenges You Need To Plan For When Moving to an SDN Infrastructure


It wasn’t long ago that racking and stacking devices was the norm when it came to adding new capacity within the infrastructure. But thanks to SDN and systems like OpenStack that virtualize compute, network, and storage resources, what was once a lengthy install process is now a click of a button and boom: new resource created.

But as Uncle Ben said, with great power comes great responsibility. The ability to add new resources on demand means that infrastructures can and will change quickly, and it’s imperative that you monitor them closely to have immediate visibility into what’s going on in your environment.

Dave Hegenbarth, SevOne’s Director of Systems Engineering Global Strategic Alliances, covered this topic at NEXT15, our first annual user conference. Dave mentions that, “we have to have tools that understand changes in real time and expand to have the capacity to monitor the statistics that new [SDN resources] will produce.” [Watch the full interview here.]

To elaborate on Dave’s point, SDN environments are a game-changer for infrastructure monitoring and management. Here are three challenges you need to plan for when deciding to move to an SDN infrastructure.

  • Real-time changes: When you’re managing a static infrastructure and all updates are manual, a nightly discovery to identify new resources that need to be monitored makes sense. But when new resources can be added and used immediately, your monitoring systems needs to update and recognize new additions just as quickly.
  • Rapid growth: Infrastructures that can expand exponentially need a monitoring solution that can grow with them. If the monitoring solution does not have the capacity to scale quickly, it can quickly be over-subscribed, leaving visibility gaps.
  • Service context: With rapidly changing environments, it’s important to monitor not only independent resources but how those resources work together. Understanding and monitoring the context of how specific resources interact improves performance and deliverability.
