What SD-WAN vendors won't tell you about SD-WAN

[@gabaseballdad]

Did I miss what vendors aren't telling us??? Seems like just general info about Cato SD-WAN.

[@madachi55]

at 11:10 - what SD-WAN folks don't tell you is network performance is a crap shoot over the internet because it's dynamically routed, paths change constantly. The trombone effect is unmanageable on a public network and there are really no SD-WAN tools that can manage it. The only defense is full-mesh or partial mesh topology. Not all SD-WAN vendors support full or even partial mesh. Without it your left flapping in the wind.

Great session 👏

I'm struggling to see good use case scenarios for SD-WAN. I guess if you only have an MPLS (Leased line) ISP available where you need connectivity and they have metered usage and charge you for using the line - then SD-WAN would maybe work. Buy a cheap FTTx DIA (Internet) line in conjunction with an MPLS leased line. Route applications which have a low QoS requirement across the FTTx line and keep QoS sensitive applications (or periods of congestion) across the leased line. IMO - the majority of the UK has cheap bandwidth and access to SaaS is unmetered and suffers little congestion. Another possible use case scenario is that you're business with an already established MPLS WAN and you wish to introduce a site across the globe and face various reliability hurdles. You could spin up the remote global site with a few different connectivity option with different providers and WAN control access to the MPLS across the globe. Would like some replies to explain some other useful case scenarios etc.

I'd guess DMVPN Is cheaper to deploy You can a virtual spoke in aws for example for IaaS, SaaS.

nice one thanks for sharing

thank for your great video

I thought you will be going to explain disadvantages of SD-WAN.

[@andysobrandy]

me too :)

Disadvantages of "other" SD-WAN

[@Prince_of_the_South]

Right

[@spoosteritservices7939]

Very well presented

[@ValcoBayrunner]

Service providers don't build out their core network fast enough, there are always bottlenecks, over utilized backhauls, and single points of failure, especially up here in AK, where the ISP network and mpls network are all on the same network.

Fortigates now offer security for SD-WANS

[@MrTheAlexy]

could you tell me pelase why we cannot use VPN spilit horizont or just routing to separete that traffic between WAN and Internet. Let's say the Main Office uses 10/8 network. Why we cannot create 2 rules: 10/8 ---> WAN 0.0.0.0/0 ---> ISP. Why would I need who SD-WAN solution for a task that can be done on ANY router?

[@zakariafarah1101]

Some advantages of SD-WAN: *SD-WAN requires less skills and maintenance - think of IPsec tunneling, IKE, NAT-T, etc. in VPN. *SD-WAN is scalable for company growth, VPN suitable for small scale site-to-site connections *SD-WAN has less latency and congestion issues, and has dynamic path selection, Qos, application-aware routing, etc. *SD-WAN can automatically fix service failure or outage by transferring your connection from one network to another. *SD-WAN can restrict traffic based on user profile or traffic type. *SD-WAN offers more network connectivity flexibility with variety of WAN connections. That said, VPN has its place in the corporate world working seamlessly alongside SD-WAN specifically for the remote workers connecting to the corporate network securely. For other applications, companies would use some form of SD-WAN, NFV, Public Cloud, Private Cloud, etc.

Hi Steve, we are an MSP based in Australia. Would like to connect with you on linkedin

[@alexandrudragomir3702]

Hi guys, you are ridiculously ignorant. You are talking about reliable internet connection and exclude eastern-europe. The most developed infrastructure in Europe is in eastern-europe where people have 1 Gig connection at home and were ADSL, CATV is obsolete for a number of years.

[@rajeshjoshi7913]

And your point is ...?

[@zakariafarah1101]

His point is that when the presenter mentioned where is "dependable Internet" he mentioned US, Canada, Western Europe, Japan, South Korea. Apparently, the complaint is that "Eastern Europe" was not mentioned. But I would argue that some countries in Eastern Europe would rival their counterparts in the West in every category including telecommunications infrastructure. But some would be lagging far behind.
