vital here is why
SD-WAN (or ‘software defined area networking’) is a changing the way multi-site
businesses (or those with homeworkers) connect and build their networks. This
post  will  discuss  the  importance  of  a  good  connection  for  SD-WAN  and  the
benefits of the technology.
What is SD-WAN?
SD-WAN is a virtual overlay that can be applied to the already existing wide area
network.  The  term  ‘software  defined’  simply  means  that  changes  across  the
network  can  be  made  using  software.  Prior  to  the  development  of  SD-WAN,
changes across the network would be more time consuming as they would need
to be done by manually altering hardware in multiple locations.
The importance of a good quality connection for SD-WAN
Software suppliers are increasingly moving their technology to The Cloud, which
(in turn) means that is highly reliant on the quality of its connection. The software
layer of the network is only as solid as the network connections they are built
on. Consequently, a good internet connection is essential for SD-WAN.
SD-WAN uses  the same connections that  you  would  with  any  other  network,
however as the intelligence is built in at the software level, it means the routers
can  be  much  more  basic.  This  has  a  huge  implication  on  the  hardware  cost
meaning  for  the  same  price,  you  can  sometimes  get  multiple  times  the
bandwidth.
You  can  also  have  your  resilience  built  in  at  the  software  level  meaning
automated fail over of load balancing if the underlying connections are capable.
It is also important to mention the need for SLA (or ‘service level agreements’).
These are commitments by your service provider.  These typically are better with
higher quality circuits and will be based around response times if the service goes
down (note it is almost never fix times!), up time for the core network and things
like time to get engineers on site. When you have so much critical infrastructure
powered  in  the  cloud,  the  quality  of  connectivity,  SLAs  and  resilience  are
paramount.
The benefits of SD-WAN
 
Flexibility
One of the most apparent benefits of SD-WAN is its versatility. Networks can be
altered extremely easily and quickly. Separate parts of the network can be altered
using  algorithms alone,  with  traffic prioritised or  re-routed  based  on a  whole
series of criteria or even machine learning.
Efficient
The control that SD-WAN gives you over your network is also makes it incredibly
efficient.  Both from the reduced costs of lower levels of human interaction and
programming,  but  also  software  companies  can  now apply  learnings  between
networks. This means that changes can be implemented instantly across multiple
locations, new sites added much more easily and changes rolled back if required.
Security
Security is vital in today’s digital landscape. SD-WAN has built in features such as
firewalls, encryption and content filtering which will stop dangerous traffic from
entering your site. It also has superb recovery capabilities.   Having a centralised
internet breakout and centralised monitoring means reduced number of firewalls
and  if  a  hack  does  happen,  patches  can  be  rolled  out  network  wide  in
milliseconds.
Cost Effective
SD-WAN will save your business money as it doesn’t rely on expensive to maintain
equipment and it has a much-reduced cost of time to maintain. We have seen
some  businesses  make  savings  of  90%,  however,  50%  is  a  much  more
conservative estimate of  potential  savings.  In  addition,  the savings form other
areas of the infrastructure by moving to the cloud can be even more significant.
