“There is no one size fits all,” when it comes to WAN - that’s according to Hussein Khazaal, head of marketing & technology partnerships at Nuage Networks.
During the first panel discussion at WAN Frankfurt, Khazaal
sat alongside fellow panelists Marcel Koenig, principal
ICT technology & sourcing at Ancoma Consulting, Michael
Huber, vice president sales Germany, Open Systems, Thomas
Lentz, solution manager of innovative services at Singtel, and
moderated by Rob Schult, research director
"One of the main challenges we see is that when you talk
about SD-WAN we always talk to network people, said Lentz. "But
if you only change SD-WAN from the networking side then their
will definitely be more costs because you are adding more
features so there is no cost reduction. We need to look beyond
the network infrastructure and get the IT people involved. We
need to look at the security, we need to look at the cloud, and
then you can start reducing your costs because then your
network becomes more agile, much more dynamic."
Weaving their way through a myriad of hybrid Wan related
topics conversation quickly turned to the cost element of such
deployments, referring to Koenig and his recent webinar on the financial impact of
"There are instances where you can reduce costs of by 50% if
you’re coming from a native MPLS network to a
hybrid environment and moving from active-passive to
active-active." The other cost driver is how do you tie those
different networks together? How do you integrate internet and
MPLS?," said Koenig.
"SD-WAN is not free, new functionalities can eat up almost
50% of the savings. If you go beyond the network to the end
user environment, there are additional costs and resources
being used up there"
With this in mind, Khazaal said that the sell for businesses
to even begin implementing this new technology is clear.
"On the service provider side the immediate benefit they see
is the speed at which they can offer the service to their
customer and because of the flexibility you can actually upsell
them a value add service. There’s the added growth
opportunity of expanding beyond their network."
On the enterprise said you get the AWS life experience, but
what we still is that more enterprises what to consume this as
a managed service. You get that visibility into your
SLA’s, you can upgrade service and you can order
value add services online etc.," adds Khazaal.
One question that kept coming up throughout the discussion
was which type of WAN solution is the best way to go?
Huber says that SD-WAN as a managed service is the way to go
because "this means we can provide the best of both worlds", a
thought echoed by Lentz at Singtel.
Koenig had a more diplomatic approach and said that the
right solution is unique to your business.
"Everyone is right from his perspective. But I think really
think it depends on the application, what they require and what
roles and responsibility model you have and who enforces
