As demonstrated, the virtualized edge and SD-WAN represent a large leap in WAN technology with many potential benefits. But such technology shifts are not easy. Whether it’s an enterprise trying to build out vCPE and SD-WAN, or service providers building their own virtual edge networks to provide customers with new services, this shift does not come without challenges.
Our survey addressed some of these challenges. When asked an open-ended question on the biggest challenges enterprises face as they manage their own connectivity, the responses centered around the costs associated with rolling out and maintaining the environment and an overall lack of visibility. Another frequently cited challenge was the complexity of the environment, which when combined with a lack of visibility, can make it hard to manage and optimize the deployment, as well as troubleshoot any issues to improve its performance.
Service Provider Plans for Their Architecture
Our survey results indicated a majority of service provider respondents want to move to a virtualized and/or SDN-based architecture for their WAN connectivity solutions. As explained, the main drivers for adopting these new architectures are the promise of new revenue streams through the introduction of value-added services, such as security, virtual management, WAN optimization, and application load-balancing.
