As an industry analyst, not since the days of WAN Optimization have I seen a technology gain as much interest as I am seeing with SD-WANs today. Although full deployments are still limited, nearly every network manager, and often many IT leaders I talk to, are interested in it. The reason for this is two-fold – the WAN has grown in importance for cloud-first enterprises and is badly in need of an overhaul. This hasn’t gone unnoticed by the vendor community as there has been an explosion of companies bringing a broad range of SD-WAN offerings to market. The great news for buyers is that there is no shortage of choices. The bad news is there are too many choices and making the right decision difficult.
