For instance, mission-critical applications
(such as payment processing) can co-exist
with public applications (such as Guest Wi-
Fi) on a single network.
By virtualising the network so that all
network intelligence is handled in software,
enterprises can simultaneously set up remote
locations and keep them in sync using
centralised cloud-based policy administration
that’s inherent in SD-WAN connectivity
models. This modern cloud-based approach
further reduces cost and complexity while
increasing overall network flexibility.

A clear path to Digital Transformation
Any enterprise that wants to get started
with an SD-WAN deployment should
develop a data connectivity and security
programme for their remote locations.
Engaging stakeholders to ensure a holistic
approach is critical to this process and a
pilot installation can quickly demonstrate
the practical benefits of a secure SD-WAN
solution. A wider, incremental rollout
on a site-by-site basis can then help to
avoid disrupting existing architecture and
minimise business risk.
Legacy connectivity architectures are an
inevitable consequence of technology
innovation and changing market
conditions. The challenge for any business
on a Digital Transformation journey is that
the changes being made to infrastructure,
services and processes are so fundamental
that relying on legacy networks will
ultimately stifle their efforts. Only a
modern approach to connectivity – such as
a cloud-based SD-WAN solution – provides
a clear path to continued business success
from the data centre to the network edge
and beyond. n
