Local application visibility provides practical networking fix for hard-pressed CIOs.

More than half (51 %) of UK-based CIOs plan to use software-defined Wide Area Networking (SD-WAN) technologies to gain crucial visibility of local network traffic and application performance issues amid severe constraints on their IT staff and resources.

Insight from SD-WAN into applications' branch-level performance is even more important to IT bosses than its cost-saving and network optimisation benefits, says research of 200 UK-based global company CIOs' by specialist integrator of next-generation technologies, Teneo.

While global companies use different MPLS, broadband and public Wi-Fi for their WANs as they expand, these arrangements are leading to local-level application performance issues and rising network costs. Since SD-WAN tools enable CIOs at the centre to find out what is going wrong at branch level, they are attracting growing interest from global carriers, networking vendors and CIOs alike. Analyst Gartner estimates that there are 4,000 SD-WAN production implementations world-wide and predicts that one third of global businesses will be using SD-WAN by 2020.2

Teneo's research found, however, that UK CIOs still face serious resourcing and skills gaps as they try to reconcile their global and local network infrastructure needs.
