Are routers the legacy hardware that's most threatened by SD-WAN?

Yes. The first would be routers. The most prevalent hardware out there at the edge of an enterprise is routers. The first piece of hardware that gets taken out is not the router, interestingly enough. It's the WAN optimizer. When you put SD-WAN in, it is solving a problem that basically eliminates the necessity of having a WAN optimizer. The WAN optimizer, if you compare what is the cost, the WAN optimization is the most expensive, so it makes the most sense to take the WAN optimizer out. But it's not the most prevalent device out there. Then your VPN device would come out, potentially your firewall would remain there depending on how you're rearchitecting your security. The firewall physical device might come out. Then the router could come out as well. The reason the router comes out a little bit late is the WAN is the lifeblood and people want to make sure everything is perfect before they take the router out. We're totally fine with that. We can coexist with the router and over a period of time as the IT department becomes more comfortable with SD-WAN and VeloCloud, then we take the router out.
