Network engineering and operations leaders
are looking to replace their traditional wide-area
network (WAN) architectures with software-
defined wide-area networks (SD-WAN) in order
to support the ever-increasing traffic demands
(and associated connectivity costs) that come
with digital innovation (DI). These DI-driven
initiatives improve staff productivity and create
new business opportunities. Yet, they also
impact networking performance and ratchet
up security concerns.
SD-WAN adoption is accelerating and many
organizations have embarked on SD-WAN
implementations. But many SD-WAN solutions
present serious challenges – from inadequate

security to high total cost of ownership (TCO).
Understanding these issues is key to navigating the
increasingly complex market for WAN edge technologies.
How DI Is Impacting Corporate Networks
Distributed organizations are embracing a wide
range of DI technologies. This includes adoption of
Software-as-a-Service (SaaS) applications, cloud on-
ramping connectivity, Voice over IP (VoIP) and video
communications tools, use of DevOps to speed time
deployment for new web applications, and Internet-of-
Things (IoT) devices for data collection and telemetry.
However, these DI initiatives present new challenges for
network engineering and operations leaders who must
sustain both performance and security from the data-
center campus to branch offices on the network edge. n
