How does this sub really feel about SD-WAN?

Of course, this topic comes up from time to time. I'm kind of curious on where people sit, though.

I've noticed whenever the topic comes up around here, there's a fair bit of hostility. People who post they are "going SD-WAN" usually get dog piled, and told they're making a mistake. I know I've personally shared some not-so-nice opinions about the technology in the past. But I'm not sure if I still feel that way.

The general consensus here seems like it's great for "mom and pop" companies with dirt simple networks and no IT staff, that could probably get by using D-Link, that it doesn't solve any actual problems, that it's just marketing fluff, and that it's probably a good 5 years too early to even look at it, because the herd hasn't thinned out yet.

Or, am I wrong, and some of you are starting to change your minds yet?

Also adding to the confusion is that there's a lot of different "flavors" of SD-WAN. There's provider managed "hosted SD-WAN." There's also "on prem" SD-WAN that an enterprise can buy and deploy themselves. I feel like that distinction throws a lot of people off, and most think of the provider managed hosted solution when they think of SD-WAN in general, even though the market share shows some of the "on prem" solutions being at or near the top.

What do you guys think? Do you know anyone who's actually "going" SD-WAN. I see a lot of people post here that they're looking into it, or maybe doing a POC, but next to no one actually rolling this out in production. Yet, there must be people rolling it out, or the market numbers wouldn't be what they are. So it stands to reason that some of you here probably do have this in production, we just don't hear from ya much!
