SD-WAN Myths Debunked: What you need to know

      Posted by Sydney Boman on Jun 29, 2017 11:00:00 AM


      One of the most important things to consider as you deploy a cloud computing solution is your network bandwidth. As businesses adopt cloud services company wide, their bandwidth quickly becomes bogged down. 

      SD-WAN, or software defined Wide Area Networking, has emerged as the next big solution in networking, working to counter the effects of cloud services on bandwidth. But with all the hype around this new technology, a few myths have taken hold in the IT community. Read on to find out the truth behind these myths. 

      SD-WAN Myths - Debunked

      Myth 1: SD-WAN makes WANs much more complicated

      With the expansion of cloud computing services, its true that enterprise networking infrastructure is becoming more complex. However, SD-WAN technology aims to simplify WAN architectures and management. While traditional networks are managed from the network up, SD-WAN networks enable management from the application down important source. This works to ensure the network delivers services more effectively while reducing costs for the end-user.

      Myth 2: SD-WAN's only benefit compared to MPLS is cost.

      As we mentioned above, the benefits of SD-WAN extend beyond the cost. SD-WAN makes WAN architectures easier to deploy and manage. Cost is only one factor in the many reasons to deploy an SD-WAN solution. SD-WAN offers plug-and-play with its edge device as well as point-and-click provisioning of services, which are huge advantages. With SD-WAN, everything is GUI based and centralized, which is much easier to work with compared to MPLS. One of the biggest selling features of SD-WAN is that it requires no expertise to run!

      Myth 3: SD-WAN is same as WAN optimization.

      A common misconception that the two are one in the same, SD-WAN is more than just WAN optimization. WAN optimization aims to reduce bandwidth consumption by using techniques like compression, caching, and deduplication. Thus, WAN optimization results in the effective use of the available limited WAN bandwidth.

      SD-WAN, on the other hand, deals with real-time traffic in a more direct way. It monitors jitter, delay and packet loss at the end nodes and will seamlessly switch the traffic to the best path available among the bonded links. The truth is that SD-WAN and WAN optimization are complimentary solutions that can be used independently or combined.

      Myth 4: All SD-WANs Require Hybrid WANs
      For this myth let's take a step back and define the difference between SD-WAN and hybrid WAN. While SD-WAN enables management of the network from a centralized location separate from the actual devices, hybrid WANs combine multiple network links at the edge. Hybrid WANs represent only one of the versions of an SD-WAN solution and there is more to SD-WAN technology than hybrid WAN deployments.

      The Bottom Line

      SD-WAN has a lot to offer companies in the new cloud age. As your business navigates its shift to the cloud, consider deploying an SD-WAN solution to simplify your networking!
