Software Defined Networking (SDNs) has been the hottest topic in networking over the past few years, and will likely continue to be over the next couple. It’s certainly dominated the traffic on this site and others.
Despite the high interest levels from network managers and the media, SDN adoption remains somewhat light. While the concepts of automation, centralized control, and programmability make sense to most network managers, where to deploy an SDN first isn’t really that obvious. From a utopian perspective, one would want to apply the principals of SDNs to the entire network all at once. Bringing in a dose of reality, though, most organizations simply can’t be that aggressive with network changes without putting the business at risk. For many companies, the network is the business, and this radical a shift, if not deployed correctly, could seriously jeopardize the business.
