 Good morning, good afternoon, good evening, and welcome to Red Hat portfolio. This is so awesome. We are an open culture that is really, really important. Everybody has something that they can say. On top of Red Hat portfolio. Hello and welcome to this week's Ask an Open Shift admin office hour stream. So today is December 15th. We are officially less than two weeks away from Christmas, a week and a half away from Christmas. For all of you last minute folks out there time to get motivated. But this is also our last stream for calendar year 2021. So we can finally say good riddance to year number two of this. Shall we say situation Johnny? That's right. That's right. I like that. Yeah, so some of you may have noticed if you are quick, quick eyed or eagle eyed and a regular watcher of the stream. I am not in my normal location today. Hopefully everything sounds fine. Hopefully it's not too distracting for you or anything like that. But turns out that having a water leak on the second floor that's then percolates down into the ceiling just outside of my office is not a good thing. So, oh no. Yeah, yeah. So Sunday night, it was, I don't know, 10 o'clock or so Sunday night. We heard water dripping in the foyer of our house, which is kind of, yes, the front door is there, but my office is right next to it. And so we discovered that there was water leaking down. We had the company come out, they tore down the whole ceiling. There's now gigantic fans and dehumidifiers and all of that other stuff running out there. My wife goes, oh, it'll be fine. We'll just turn off everything while you do your stream and all that other stuff. And then it turns out that, no, like the insurance adjusters and the remediation company and like a whole bunch of other people are all coming basically during this time. So hopefully the dog does not go crazy. If you've watched, you've heard the dog go crazy before. So she's in a whole other section of the house today. Well, if they want to talk to you, just bring them on. We'll say hi and ask them some questions. So anyways, speaking of today. So today, as I said before, this is our last stream of the year. And we've got an interesting kind of smorgasbord of topics. So the overall topic for today is troubleshooting. It's something that is near and dear to my heart as a long-term administrator, right? It's something that we all do, whether we want to or not, right? Because everything always goes perfectly according to plan. But it's something that I want to talk about. I want to have an open conversation with you all with our audience. Please feel free to ask questions at any point in time. It's the point of the office hours is for you to ask us questions. But we are also joined today by Mark Schmidt. So Mark is one of my peers on the tech marketing team. He specializes in a number of different things, not the least of which is Telco. And if you are familiar with Telco, they do some things with networks apparently. And this therefore makes him far more of an expert than I am when it comes to things like SDNs. So I asked him to join us because we want to have a short conversation here up front about SDN, OpenShift SDN, OVN Kubernetes, et cetera. So Tanewa, so yes, apparently AWS West. So I think Oregon and California are having issues. So me trying to log into Twitch a little bit ago was an exercise in patience. So if you are watching the stream and you have anything in AWS, looks like Oregon or Northern California, you might want to keep an eye on your monitoring dashboard and make sure that nothing's going on over there. I wish that OpenShift could help with AWS outages. Unfortunately, or fortunately, depending on your perspective, we can only do so much. So, Johnny, any thoughts, anything? No, I'm just looking forward to the break. It's going to be a nice little end of year, to cap the end of the year with some time off and hang out with family and stuff like that and try and get the energy back up for next year. I'm looking forward to it. And Mark, nice to meet you. Looking forward to it today, so it's going to be awesome. Nice to meet you too. Yeah, I know. Usually we do introductions a little more in our little green room thing, but everything's been a little rushed this morning with all the stuff going on. And I've been having fun. So I said I was relocated, right? I'm upstairs for today. So I actually commandeered my son's gaming computer, which is, so don't judge me. It's Windows 11 based. It means I get to do fun things like use NVIDIA Broadcast. So if I go like this, the camera will follow me automatically. Nice, nice. So if you notice the camera doing weird things, that's NVIDIA Broadcast doing its thing. I thought that was kind of neat. Yeah, so please don't get too distracted by me. Anyways, so let's talk about the top of mind topics. Let me find the right document here. And since Mark is here and Mark, I know you've been having some, some laptop issues of your own that are resulting in a repair person coming to your house. I want to make sure that we cover this topic up first. And it's something that I have seen come up quite a few times actually in the last couple of weeks. So with OpenShift, I think it was 4.6, 4.6 or 4.7 was when we first supported OVN Kubernetes, fully supported OVN Kubernetes as the SDN with OpenShift. So OpenShift SDN has been the default basically since like OpenShift 3.0 or something like that, right? It's been the default for ages. However, OVN Kubernetes is scheduled to become the new default at some point in the future. So originally we thought it was going to be 4.9 when that change happened that got pushed back. So it might be 4.10, you know, predicting the future is hard. So hopefully it will have been in 4.10, but if not, that's okay. So I wanted to ask you, Mark, because this is something that's come up again multiple times. What are some of the key differences between OVN Kubernetes and OpenShift SDN? And what are some of the kind of highlights of why I would choose one versus the other? Yeah, I guess straight up why we're doing this. We're kind of consolidating our networking around OVN from cross-product portfolio perspective, right? So OpenStack as well as OpenShift are going to be using OVN as well. Feature-wise, it's very similar to OpenStack.
