With the network accepted as a critical element of business operations, preparing for failure is also critical. Derek Watkins of Opengear explains. With so much focus on SDN and network feature virtualization, many network designs and implementations are missing elements that are essential for both reliability and resiliency. At the most basic level, every network element needs to be easily accessible by the network admin team who are responsible for updates, configuration changes and inspection, yet many lack these tools, and this in turn hampers modern network administration practice.
