 Hello, everyone. Welcome to another episode of Open Infra-Live. We love getting the community together on YouTube and LinkedIn and everywhere else that we can reach on the show every week. So today's episode is super exciting because we're going to be talking to some industry experts from Bloomberg, G-Research, Line, and OVH Cloud about their sessions for the upcoming summit. We're so excited to be getting back together in person after being apart for so long and that summit will be in Berlin in June. So we really want to make sure everybody here gets a little sense of some of the awesome talks that will be happening at that summit. So it is in Berlin, June 7th through 9th. We got some information here on the screen and the price increase is the price, the ticket price will be increasing soon. And we're just excited to get everybody back in addition to these speakers today who are going to be a little preview of their presentations for the summit. We also have some amazing speakers from China Mobile, BMW, Volvo, Kakao, tons and tons of great speakers. We've been confirming new speakers even in the past week. So we'll be continuing to let you know who else is coming and when to be there. Now, in terms of registering, we decided to do something a little crazy today, which is to give everybody who's tuned in to this broadcast a 20% off if you register today. So there's a code OILive2022. So if you're watching this on recording, I'm sorry, but you should have joined live. But this is why we love to get everybody on the live stream that we can every week. So we got a little something special for you if you did tune in if you're on live. So this code is something you can use and you've got to use it today. So that's your that's your chance. And if you've already registered, maybe you pass it on to someone, you know, a colleague, a customer, whatever. The link is that will take you to the event right to registers. This bit.ly slash open info summit that's on the screen here. You can also go to open info.dev slash summit. Just read more about the summit. Look at the full schedule, all that kind of stuff. So that is what we're here about today is getting hyped and ready and prepared for the summit. And to do that, we're going to bring on some amazing guests to talk about what they're going to be sharing more about at the summit. So to start with, I want to bring on Ross Martin, who is going to tell us, dude, where's my VM? Hi, morning, everyone. Yeah, so just a quick bit about me. So my name is Ross Martin. I'm joining you from just outside of London. I work at the cloud engineering team at G research that joined there about three and a half years ago when we created the cloud team. And I personally focus on open stack private cloud and stuff. I've been working with open stack since 2014 where I've built a small public cloud platform in the UK for a company called Memset. It's fairly successful. And sometime later, I've made the research to start work on a Greenfield private cloud project. And we've been having lots of fun. So who's your research? We're a leading quantitative research firm, mostly based in London, but we're actually looking to expand to Texas soon. We create software to analyze and manage large data sets. We identify patterns in this data using the latest machine learning techniques and try and predict future movements in financial markets around the world. As a company, we're a huge proponent of open source software, choosing this route wherever it makes sense to. And we're keen to push back upstream where possible. We've even got a considerable in-house open source team to help us do that. We're responsible for a couple of significant features in open stack recently, mostly in colorizable. Lots of my head is vault integration for managing secrets and TLS encryption for end-to-end API encryption, which is really cool. And we've got about 10,000 lines of code merged now. So why talk about scheduling? So from an open stack compute perspective, like we're running multiple regions, multiple AZs, continuing to expand at a quick rate. Initially, we had quite a simple estate, just some VMs in a single region, but we've been through quite a significant period of growth. And we've been adding lots of capabilities for things like GPU and NVMe. And recently, actually implementing Ironic with lots of different types of hardware configuration or resource classes in our terms. This means we've now got quite a reasonably complex cloud, over 150 flavors. When you couple that many options with some of the internal goals that we have at GR, like the ability to rebuild every server every 30 days and still keep the cloud efficient and running, you know, we've got one hell of a game of Tetris going on. So it has been, it continues to be a challenge. And based on our experiences, we just want to share with the community some of the techniques and features we've used to help deliver this cloud. And I guess, what would we want you to take away? Well, you know, come to this talk, pitched at beginners to intermediate operators, if you'd like to learn about the basics of how the scheduler works, how the traits API works, host aggregates and how they all fit together, as well as some configuration examples and automation examples along the way. So if that sounds interesting, then this talks for you and if not, then maybe it isn't. There's a fair few of us attending the summit this year. So if you see any of us, come and say hello. My colleague Scott and I will be delivering this talk. Dude, where's my VM? Although it should be instance now doing ironic on the Thursday about 10 past 11 on room B09 and will be around for a chat after. Well, that sounds super cool. I was going to ask you a couple of questions. One, did you say you're expanding to Texas? Did I get that? Yeah, it's quite a recent thing, but we are hiring. So yeah, jump to the website if anyone's interested in that area. Well, I'm coming to you live from Austin, Texas right now. So, you know, I'll have to find out more about your expansion plans coming into the great state of Texas. So more of a question for you on your cloud and your talk. You're talking about how you have some different flavors or instances for different workloads, kind of the generic standard sort of virtual machine. And then you also, I think, have some workloads that really demand bare metal. Can you talk about kind of why you need different types like that and how people decide which is the right one to use? Yeah, I mean, for us, at least at GR, we kind of get a generic instance, just like you say, just to run with the MilVM sort of KVM defaults. Our users might use that for development workstations or proof of concept work or kind of simple applications testing. But a good example of like a specialist workload would be a service we run internally called Armada. GR is actually open source this. You can find it on GitHub. It's a tool for scheduling and running batch jobs over multiple Kubernetes clusters and it's capable of scheduling hundreds of jobs per second, so I'm told. So in that example, we would use bare metal machines to get the most performance. And in our case, we'd use Ironic and deploy steps to configure that and to configure the BIOS to give them the best performance. That's really cool. Yeah, I think one of the things that I love to learn about from users, especially, you know, at each summit is all the other open source that you've created and you're sharing that sort of works alongside open stack or other other Kubernetes other popular open source tools to kind of make it all work. Better together. And so hopefully we can we can learn. I can catch up with you at the summit learn more about that. So thank you so much for the preview of your talk also for everybody on the live stream. You should drop a comment. Let us know where you're joining from, you know, we just our guests today we have from joining from all over the world. And I'm sure those of you who are on the live stream are joining from a lot of different countries. And that's always fun to share and get to know how many different countries we're talking to today. So thank you for that. I want to next bring up Styler Tyler Stahecke and find out how he flipped the cloud. I don't know. I want to hear more about this from Bloomberg. Yeah, Mark. Thank you. So while we architected the latest generation design of our private open stack clouds to scale up from the get go, we started our, you know, state like everyone else from a group with a Greenfield cloud from ground zero. No VMs and a moderately sized control plane, almost unsurprisingly, once people got a chance to play with open stack, things really started taking off. What our metrics were telling us is that not only were we growing fast, we were growing really, really fast for anything as a cloud infrastructure team. We had internally witnessed in the past. So we quickly found ourselves needing more controller hosts. There were some parts of the control plane that we had to optimize a bit for our use case and things of that nature. But here we are a couple of years later with tens of thousands of VMs and a single cell and we're ready for more. And the secret driving force behind this is data and metrics. Our founder, Mike Bloomberg, often says, if you can't measure it, you can't manage it. So regardless of whether you're aiming for a modest deployment or aiming to scale out to thousands of VMs and beyond, it's a matter of when and not if you'll start uncovering stress points and be contending with hardware failure, network hits and other kinds of things. So let's talk about one of the stress points we hit when scaling for a bit, because that's particularly interesting and along the lines of what we hope to discuss with members of the community this summer in Berlin. Off to the right is an exciting example of one stress point we found and addressed. So for some backstory, this past summer, we had been developing and rehearsing some open stack point release upgrades to our clouds. And while we were doing so, our metrics started telling us that our databases were starting to build up some pressure. And the last thing we wanted to do was go into an open stack point release upgrade, which required database scheme upgrades with database pressure. So kind of like looking for a quick win. And very quickly, we were able to identify that most of the database pressure stemmed from the Nova metadata service. And so with maybe a hundred lines of Ruby and Python, we were able to codify a deployment that targeted that specific issue. And while it almost dropped our database compute load in half and reduce the request latency for uncached Nova metadata by almost an order of magnitude. And so that's super exciting. What really led us to this issue early and told us where the squeaky wheel was was the data metrics we had collected. And so this dovetails a bit into the second bit of advice that we'd kind of like to discuss. And that's when you have an open stack cloud in production. You're going to need to optimize it, expand it, upgrade it, whatever you may be doing, you can't afford to guess in production. And even when you have a modest cloud, you have to stay agile because open stack has six months release cycles. It's a really agile project that moves quickly. So at the end of the day, you have to cope with in order to cope with this, you need CIC pipelines and you need to be able to spend a development clouds that look and feel like your production systems. When we did that same series of open stack upgrades this past summer, we broke a lot of development environments, finding out what worked for us and what didn't. Fortunately, because we had those and they resemble our production environment so closely, we were able to seamlessly upgrade both staff and open stack on our single cell clouds in a single maintenance window on the weekend with no impact to the VMs, but also zero API downtime or any impact of any sort. And I say that like it's extravagant, but really for us, these uptime requirements are a must and not a nice to have. So we'd kind of like to show the community and work with the community to see what we've done and hopefully convince more people that open stack is a great solution for private cloud providers. Well, thank you. I'm convinced, but I might be biased, but no, this is great. I mean, we have been excited to follow the Bloomberg journey for a while. And of course, being able to share it at the summit is the best place, but it's great to have a little preview here on YouTube and LinkedIn and everywhere. I guess my question really you touched on this already a bit, but you've went from relatively small cloud to just massive, massive scale with open stack. So for people that are at that earlier part in the journey, you kind of mentioned CICD and things like that. But what type of advice do you have for people to kind of prepare themselves for that massive explosive growth that often happens once you give developers access to that kind of infrastructure? Really, it goes back to the, you know, if you can't measure it, you can't manage it. You need metrics on everything. So, you know, the kinds of issues that we see even today still in production environments, it's just not things that you expect. And without the data, you know, you can't alarm, you can't see those issues. You don't know which part of the system to turn to next. So even if you're a small cloud, you really need to kind of have eyes on everything. So, you know, what, you know, what direction you need to go in. Okay, awesome. Well, I think to make sure we get enough time for everybody, I'm going to move to the next speaker, but we're going to bring everybody back on at the end so we can take more questions from the group. But our next preview of their session summit for the Berlin summit, we are excited to hear from Lide and we have Radiff and Yushiro. So please take it away and tell us about your session. Yeah, thank you, Mark. Actually, I think our session has something in common with Bloomberg's like how they blew up the V and how they blew up the cloud. So, last year, basically, we at LineCorp, we started to figure out effective ways to actually understand how our system is basically scaling. And what are the various points, checking points of matrix and what are the various indices which we have in our system. So like based on the SRE Bible, which Google has released earlier and with coordination with our in-house reliable team, we were able to formulate a set of key indicators that can be used to demonstrate how our clusters are performing, how the systems are performing effectively or not. So this result in project was which we called as a cluster monitoring project from our site. We developed it and we were able to deploy it on all the regions which are underline. And we were able to do it for both the test as well as a production cluster. We included various matrix in it, which included not only the API matrix, but also Kubernetes, master queue matrix, hypervisor, control plane and so on. Using these metrics, we were able to integrate the solutions and we were able to readily get the information. And using open source, some certain open source tools and certain in-house solutions, we were able to utilize that data, which we are able to gather and push it to Prometheus. With Prometheus, Elasticsearch and other components, we were able to visualize that data onto Grafana and we were able to then monitor and understand what are the various points where our system is basically working properly or whether there is some problem which we can experience or not. We did have a lot of outages while we were expanding and we are still like expanding and we see there are multiple issues which we can observe. And the objective of this project was to make a sense of all the available data which we have and to understand how these clusters are operating at scale and what we can do to improve the functioning of the clusters. One of the main decision points which we had for our like OpenStack cluster was using RabbitMQ and I think we are all aware of how stable RabbitMQ is at scale. However, we did have multiple outages, not only with RabbitMQ but also with NOVA, IPI and other components of OpenStack and using this cluster monitoring project, we were able to understand our system better and we were able to identify various issues which existed in the clusters. Next, I would like Yushiro-san to explain further. Okay, so my name is Yushiro, working at Line Corporation as an infrastructure software engineer with RayDip-san. So in our presentation, we calculated the ratio for VM operation like create, delete, reveal and so on and API response by using Message2 and visible on Grafana dashboard. So then our team defined some SLO for line cloud platform for the first time and we are now managing our private cloud to achieve our SLO. So here is just an image about the Grafana dashboard. So this is our development environment data for past 30 days so that we can see by visible on the Grafana dashboard, we can understand how many VM is created and how many times a VM is deleted in one day, one month or past six days or something like that. So for our previous presentation, we explained how to calculate them and how to correct from the metrics data. So in this presentation, we will share our operation result for six months and some point and to use these values. And this is a final topic of structure monitoring components for multi-region. So then most of you are using OpenStack and about some private or public cloud service. And the important point is some monitoring cluster. Of course, yes, but the much more important thing I think is the availability of monitoring component itself. So once the monitoring service has that so that no data is consumed and we cannot see that actual cluster behavior correctly. So always getting the monitoring data is the most important. So in our presentation, I will share that actual monitoring structure. So how from the service deployed on the Kubernetes layer or how load balancer is configured or something like that. So for the conclusion, I will say about the expected audience. If you are interested in some monitoring OpenStack cluster or calculate some SRO and some, if you feel some pain points to manage like kind of laboratory or OpenStack as a component and if you want to talk with us about some outage handling or something like that please come to Berlin and join our session. Yeah, that's all. Thank you. Well, thank you. The first question I had actually because I know that line is massive service but certainly in Japan everyone knows about it but it may be that some people on the live stream aren't familiar with line. So can you actually just explain what line is? I think you have 170 million users or something massive application. Like what does line actually do for end users? Okay. It's a messaging app, I believe and many more things. Is that kind of what it's used for? So it's not just a messaging app. It's a full blown ecosystem. So line has multiple services. It includes line messaging but it also has line music, line pay and there are a lot of other services as well which are currently working. There are about 84 million users who are currently using line in Japan. If I remember correctly, Yushiro-san, can you please correct me? Yeah, maybe so. Please go ahead. So we are now providing some new delivery services, kind of demo account like that and a bunch of users are using right now. So the more kind of user is maybe 188 million user and kind of the line message is maybe 4.9 billion messages in daily or kind of like that. Wow. Huge, yeah. So billions of messages every day and music are connecting people and it's all powered by OpenStack. I think that's like super cool for people to know that these everyday services that people rely on can use OpenStack infrastructure on the back end. The users might not know but I think it's really cool. So I do have a question on the actually OpenStack side. So you talk about outages and you had to deal with them and try to prevent them. What are some of the most common sources of outages for people to be aware of? Rabbit and Q. Yeah. That seems to be a common one I hear all the time and I know we've met with your team in Japan and that seems to be the most common. So hopefully we can all come together and talk about that at the summit and how to avoid those kind of issues. It seems like you've found a way to manage through the issues even with Rabbit being a problem. So Rabbit and Q is definitely one of the issues but we are using our project not only to monitor the messaging queue but also to monitor other issues as well. So sometimes for example if we do have an OOM killer on the control plane or for Kubernetes or on a hypervisor or maybe for any particular let's say neutron agent or an over compute site we are able to monitor those things as well and understand and find out what the reason was. So even in the back end if there is a problem like an out-of-memory issue we can at least monitor it on the Graphana dashboard and go back and try to solve that issue. Good. Well thank you. I know that your session I have a feeling will be very popular at the summit. I'll definitely be there. So thank you again. Again we're going to bring everybody back on at the end but we have one more session and a couple of the speakers that are joining us to tell us about it. So this is from OVH Cloud who by the way is one of the sponsors of the summit. So thank you to OVH for sponsoring the summit. And for this session we have a couple of speakers. We have David and Mohan Kumar. So please welcome on the stream and tell us about this session for Belin that you're going to be presenting. Thank you Mark. It's great to be here. I'm really excited for the Berlin summit and I can't wait to be there to share our story about our three years long journey that led us to the point when we introduced our free services to our public cloud offer. And by all three services I mean stuff like virtual routers like floating IPs and external gateway. So about integration of these three components of OpenStack Neutron we'd be talking about on our session. And I think the key point why we'd like to share our story with the community is our unique scale. OVH Cloud have OpenStack spread around 30 regions with 1,000 compute each region. And in total it is more than 400,000 virtual machines running every day in our cloud. And with that scale in mind adding new component or even enabling part of a component since virtual routers were enabled in OpenStack Neutron for a long time. But for us it's not just changing some APIs, it's not just changing some configuration. We had to make a lot of preparation, testing some adjustments to make sure that it works fine. It doesn't break anything currently working. And that the new features are also stable and are in good condition for our customer to use it. So to give a better understanding what we had to go through, how we went from point A to point B when these new services provide for customers, we'd like to take our audience with the journey with us. And we'd like to start with telling how our network stack looked like three years ago. So we'll take everyone back to the year 2019 where our infrastructure was based on OpenStack Neutron. And at that time we have our own networking agent that was sitting on every compute host in our cloud with huge technical depth because we made a lot of our changes to it to suit our need. We also introduced two new types of network, one for public network, one for private network. And it just didn't quite suit L3. So we decided that we can't go with such kind of architecture, we need to change it. We spotted some challenges with changing it. And I let Mohan to talk about these challenges and these changes that we made. Thanks, David. Myself Mohan Kumar, a working as OpenStack developer along with David for OVH Cloud. First, I would like to talk about some major challenges we encountered. First, we need to skip our multiple releases to get working L3 services. Then we need to split agents as well. So to make it adaptive for our own custom, private and external networks. At last, we have to adjust the existing code around L3 agents and drivers to make it fit for our cloud. So these are three major challenges what we encountered. And we like to talk in brief like how we were able to solve the challenges and the issues what we seen in the protection. Then we started our beta. So in the beta state, we see again some stability issues around router state, the agent communication. For example, the agent restart taking such a long time. So it make it other services to get sync with the L3 services and to make it work. Again, we are able to get some other issues basically around the scalability of our cloud and the messaging queue around agents and drivers. So in this beta state, we are able to mitigate these issues with the help of our expertise scene. I will encourage and invite audience to get our experience and the scalability issues and how we are able to solve those issues. So again, to highlight few of our future plans, so we soon moving from beta. And we also try to add a few services using L3. For example, we try to add HRJ proxy as a service using our L3 services. And again, the next future plan is something like update to new OpenStack version. So currently we are running a stain in our protection. We soon try to move to our recent OpenStack release to make use of the recent code bug fixes went through around L3 services, scalability part. So to make better use of the code change, we try to soon move to new OpenStack version in the production. Great, great. Well, thank you for giving us a preview. I wanted to go back and double check the number I heard you say. You said, I know this is one of the biggest public clouds in the world, OpenStack powered, of course. How many machines did you say you're managing with OpenStack? You mean virtual machines? Virtual machines, yeah. More than 400,000. Wow, that's incredible. 400,000. Well, that's insane scale. And it sounds like you've learned a lot along the way. You were talking about the L3 services. And why didn't you start with that at the beginning? What caused you to approach it in the sequence that you did? So basically, there's like historical reasons. But OVH, when we started with kind of public cloud providing, first we had our something that we can call bare metal as a service. It has nothing to do with OpenStack or with Ironic. It was our own software. And in bare metal world, like when the client orders a bare metal host, he gets this host and he gets the IP address associated with it. And then when he gets to that host, he can list the IP address, he sees it. And we have a bunch of clients using that model, very happy with it. So when there was a decision, OK, we want to provide a virtual machine-based cloud. And which is OpenStack, we decided that we would like to have similar experience in terms of networking for our clients. So then we decided, OK, so in OpenStack, there is like this. You have a private IP and you are hidden behind either external gateway or hidden behind floating IP. And it's not the same as in bare metal. So we decided, OK, we need to have our own network type, our own agent that would suit this. So it would be similar experience. So that was from the beginning. But then we had clients coming and coming from, for example, different OpenStack-based clouds that they have some automation. They say, hey, my automation is not working. I need to change it. So we decided that we should have two models working side by side. OK, yeah, that makes a lot of sense. And probably a lot of other users out there have similar kind of customer requirements or they started with other environments before they embraced OpenStack. So that's probably a pretty common scenario. I think I was super lucky to visit the OVH headquarters in France a few years ago. And one of the things that I learned about OVH is that there's a lot of innovation, not just in the software and the services, but actually in the hardware, in the data center. So I don't know if you all can talk about that a little bit. But I think it's really interesting the way that OVH actually manufactures its own server designs, data center designs to drive more efficiency. Do you all want to talk about that at all? Yeah, I'm not an expert, of course, in that part of industry, part of OVH cloud. But, yeah, we are manufacturing our own servers and our own cooling to drop the cost. And, yeah, it's kind of like water cooling. So that helps drop down the efficiency, the power consumption and drop the user of our electricity bill, basically. Yeah. Green cloud initiatives. Yeah, I think that there's a lot of people that are very interested in how we can be more efficient with our data centers given all of the challenges we have around the world with power consumption and climate change and all that. So the Green Data Center, I think we actually have had episodes on that and may have some future ones on this for the show because it's a topic in and of itself. But I know I kind of put you on the spot on hardware, your software team, it's just a cool part of the OVH story and for those who aren't familiar, it's kind of fun to talk about. So I think that with that, we are going to bring everybody back on the stream and see if we can go into Q&A here and see if there's any questions that come in from the chat and so if the rest of the guests can come back on screen, this is awesome. We have people from all over the world who are going to be coming together in Berlin in June and I guess my first question would be how many of you have been to Berlin before? None. Okay. Oh, we got one. Sorry. Yeah, no, I came to Berlin. Was it 2019? I think it was the last time. Yeah, great city. Had a really good time. Enjoyed the summit. Recommended. Good. Well, for everybody else, I think you're going to love the city. I really love going to Berlin. They have just incredible kind of music and art and culture and all kinds of other things going on as well as being a tech hub with a lot of super smart developers doing interesting cutting edge stuff. So be great for everybody who hasn't been to have that experience. So I know that many people will be coming to listen to your stories in depth. And I think that, you know, as somebody said in chat, that this feels like a super fast summit on fast forward that we're having today. It's kind of like, you know, every session in three minutes. So we'll have a little more time to slow down when we get to Berlin, hopefully and learn more about what you're doing. But I'm curious what people or topics you're interested in learning about, not just what you're sharing, but who you hope to meet or what topics you hope to dive into. Does anybody want to take that? Sure. I guess just listening to some of the other presenters here today, I mean, OVH Club with hundreds of thousands of VMs is, you know, it's always exciting to talk to other industry experts, you know, in areas within, we're focused on things like private cloud, public cloud, you know, all those topics. But also just, you know, what other people are doing with OpenStack, how they're using it, what issues they're running into. And, you know, what's great about OpenStack is just the sense of community that, you know, provides. There's all kinds of people, as you've mentioned, all over the world. It'll be fun getting to know everyone. You sure? Oh, it looked like you were going to jump in. Do you have a topic you were looking to learn more about at the summit? Yes. For my side, so that maybe the last time I joined the OpenStack summit was that maybe I ran PTC or something. So the very long time. So currently I'm excited to join OpenStack itself. And hopefully that, yeah, OVH clouds about infrastructure and cell infrastructure, I'd like to hear about some outage handling and large-scale rabbit MQ or something, some hyperbiter scaling way. I'd like to know about that. Yeah. Very excited. Good. Good. Anybody else? I feel like I'm sort of repeating the others. But yeah, I think for our whole team with the last year or so, just working on scaling our cloud up, it's the same really. We just want to find out what other people are doing, pain points, you know, the kind of operator wall story sessions that you have. Super interesting to us. So yeah, just coming to learn and find, learn from your mistakes really. Yeah. Good. Good. Well, thank you all to our guests today. I think that we are all heading, I know that we're all heading to Berlin and we want to make sure that everybody else who's interested gets a chance to come. And so I will just say thank you to all of our guests today and just remind everyone in the audience that we are doing this crazy one-day sale, 20% off. If you register today with this code OILive 2022 on the screen. And if you go to the bit.ly slash open in for summit, I'll take you straight to Eventbrite or you can go to openinfo.dev slash summit, see the whole schedule. Find out, you know, what sessions you're most interested in. And I think that that is a wrap for our conversation today, but I do want to tell you a little bit about some of the upcoming episodes. So you obviously heard from some large scale users today. We've had a number of episodes that have been very popular on open in for live about large scale from the large scale. And the next episode is April 14th. And this is 1400 UTC 9 a.m. central time. So you can figure out your time zone, but it's the same time we have it every, every session. And it's going to be a deep dive on Yahoo. So Yahoo is another user that has insane, insane scale and has war stories and scaling tips and all kinds of stuff. So be prepared to come in to that and ask them hard questions because they enjoy that. And I also want to thank all of our member companies. These are the members that are backing the open in for foundation and make everything possible. If you want to become a member, there's a guy named Jimmy MacArthur who'd love to hear from you. You can book a book a time with him at any meeting with him at any time. And he's our friendly guy standing by for anybody who wants to talk about membership. And just remember that we also want to have many more future episodes of open in for live. And you can submit your ideas for episodes at ideas.openinfra.live. And you just go to openinfra.live. You can learn about upcoming episodes or submit your ideas. So thank you everyone. And we will see you next week on Open In For Live. And I will see all of you in Berlin. Thank you so much.
