As a pionniers of SD-WAN (short for Software Defined Wide Area Network) implementations in Poland we know the pros but also cons of SDWAN migration from traditional WAN. As in general we think the SD-WAN is kind of revolutionary approach (dissagregation of data and control plane) we stick to the ground and as experienced network engineers can point out many kinds of potential issues on the way to “softwarize” your WAN. As much has been said already, the power of SD-WAN from IT department view is:
Above points could prejudge in many cases and force decision makers to buy SD-WAN solution. For example pure calculation that compares the resignation from dedicated MPLS service and switching to SD-WAN , where the later is based on chepaer Internet and LTE links can easily convict that SD-WAN is the right way in long term. But we can see some specific situations where SD-WAN not necesserily can be of good choice. Good old DMVPNs of GETVPNs structures can still do the job for you. For example, when you have nice DMVPN design and automation (for example written in Ansible) and you do not realy need app based routing or two Internet links in the same time utilization. It might be that SD-WAN is not the best choice for you at the moment. As said in most cases it is, but anyway you can trust Grandmetric network experts on the way to migrate your WAN to SD-WAN and that they will objectively point you and your organization to right direction and take care of the details like licensing, appliance and virtual appliance choose and so on.
