Security remains a major concern. The fact that businesses continue to increasingly move workloads and applications to the cloud has only exacerbated anxiety. Certain applications are sensitive to network latency, for example Visual Studio on Azure. GlobalData has observed that several services companies interviewed (November 2017, GlobalData enterprise survey) are looking to implement SD-WAN with one of the objectives being the reduction of reliance on dedicated MPLS circuits to all sites. The goal here is to connect smaller outlying branch offices that may have around 30-35 users via low cost broadband but without overly compromising on network and applications performance. In terms of speed and operational efficiencies, SD-WAN delivers network templates and scripts that are already defined, and the automated processes of network changes can be enacted without interfering with the existing network and IT of the individual sites. |
