Software-defined WAN (SD-WAN) and Internet of Things (IoT) go together like chocolate and bacon -- an inspired, if not an obvious pairing. That's according to Mike Fratto, senior analyst with Current Analysis Inc., in Washington, D.C., who writes in a recent blog post that SD-WAN can help meet many looming IoT challenges.
IoT includes an array of technologies -- such as command networks, industrial Ethernet, SCADA devices and sensor networks -- that can face serious security threats when connected to public networks. According to Fratto, SD-WAN products can address such IoT challenges efficiently and economically, consolidating network functions -- such as encryption, policy-based controls and routing, among others -- into one control interface. He writes that centrally managed SD-WAN technology can also minimize the need for technicians to travel to remote branch office locations to maintain a growing number of IoT devices.
Fratto highlights two major stumbling blocks preventing SD-WAN from meeting IoT challenges head-on. Firstly, high licensing costs may make SD-WAN field deployments at scale prohibitively expensive. Secondly, existing SD-WAN product hardware is not hardy enough to withstand certain on-site hazards, such as water, heat and electrical interference. In Fratto's view, SD-WAN vendors' best path forward is to partner with IoT vendors and integrators to add their technology to existing hardware.

VMware's Operations Transformation Services
Network virtualization deployments often call for radical change in the way organizations operate, which can cause problems for teams accustomed to working in siloes. In a recent blog post, Dan Conde, analyst at Enterprise Strategy Group Inc., in Milford, Mass., writes that a lack of team flexibility and collaboration can, in turn, threaten the overall success of deployment.
According to Conde, VMware's Operations Transformation Services attempt to ease such transitions, minimizing growing pains and maximizing the benefits of new technologies. In his view, these services are most valuable for organizations that have invested in VMware products, such as NSX, and want to optimize the technology in question by adjusting internal organizational structures and operational models. Conde adds that the service can also help with combining modern and legacy applications in software-defined data centers.

NS1's traffic management software
NS1, a managed domain name system provider, is using traffic management software to accelerate delivery of mobile and Web content for its customers, according to Packet Pushers blogger Drew Conry-Murray. Conry-Murray discusses NS1's traffic management software, Filter Chain, in a recent post.
Filter Chain analyzes data metrics -- including network loads, bandwidth commits, service points and user location -- to determine an optimal traffic route for a given request. Conry-Murray writes that the software can also take into account individual customer requirements.
