SD-WAN isn't for voice?
Correct me if I'm wrong, but I didn't think SD-WAN was really an "alternative" for voice apps (for cost savings)....

@mhhf1ve I think you are right, but everyone trying new tech - hopping to save

Re: SD-WAN isn't for voice?
Yes, one of the drivers to implement new technologies is always cost savings. In our experience the cost savings associated with hybrid networks (and SD WAN type functionality) can be significant, but there are a lot of things that need to be considered. The price differential between internet and private networks is not as significant as it used to be. How that differential plays in any given environment is dependent on traffic flows (how much data is destined for the internet) and security requirements (does the customer security policy allow for split tunneling at remote locations) among other things. As with anything, it's not as simple as it might seem at the outset.

Re: SD-WAN isn't for voice?
My comment on voice has to do with the fact that in most SD WAN solutions use encrypted paths to manage traffic. Orange Business Services sells SIP (called Business Talk) as part of our network solutions, and customers can recognize 20-40% cost savings after rolling their international voice traffic over to SIP. If a customer uses a SD WAN solution and encrypts the path, then we can not provision SIP trunks. To be fair there are some SD WAN solutions that can send certain traffic in the clear, which would preserve the ability to use a carrier like Orange for global voice. It's just something that needs to be considered as decisions around SD WAN are made. The same issue appears with private network access to public cloud platforms.

Re: SD-WAN isn't for voice?
Thanks for the clarifications, John. Much appreciated. I didn't know there were SIP solutions that worked with SD-WAN. Good to know.

The part about SD-WAN integrating and the internet and hybrid networks is very interesting.

Re: SD-WAN Discussion
We have been supporting what we call "Hybrid Networks" (integrating internet and private networks) for years now, this new Software Defined world brings an improved level of visibility, automation and control at the application level. As we get deeper into SDN/NFV, SD WAN type functionality will simply be another network service. The key is developing a Next Generation network design today that can incorporate all the various software defined solutions into a common orchestration platform.

Re: SD-WAN Discussion
@John Do yiou find that most businesses prefer hybrid solutions? I see many refernces to it as offering the best of both worlds. Is it perceived as such in the real world?

Re: SD-WAN Discussion
Orange serves mainly multi-national/global organizations, within our customer base I would say the majority, but certainly not all, have embraced some kind of hybrid network design. That could be using internet and IPSEC as a back up/offload or less likely using split tunneling to push internet traffic directly from the site to the internet.
The main deciding factor on how far a given customer will go depends largely on their security policy. Many of our customers have policies that preclude them from doing split tunneling or even having internet anywhere but in their data centers - that obviously limits the possibilities.
I often ask customers what percentage of their WAN traffic is destined for the internet and it's typically between 50 and 80%. Using expensive private network to transport that traffic isn't the most cost effective solution. These percentages continue to grow as customers leverage SaaS and IaaS - which puts "mission critical" applications outside the private network.
I'm not advocating for a specific design though - security policies are there for a reason, we have to play within those boundaries.

Re: SD-WAN Discussion
@John thanks for the thorough response. Are the industries generally specific to industries to to particular regions? For example would the stricter data privacy regulations in the EU translate into businesses having to keep more of their network data private than in their American counterparts?

Re: SD-WAN Discussion
I am not an expert on data privacy, but my understanding is the laws are more about data storage rather than privacy during transmission. Obviously IPSEC does encrypt the data during transmission.
Re: SD-WAN Discussion
@John: It generally depends upon particularized circumstances -- especially in highly regulated industries (e.g., warnings, history of prior intrusions, etc.) and related rubrics (e.g., HIPAA).
