 So, thank you everyone and welcome again in this awesome, awesome album and just a little bit story behind me and Mark and Jonathan we met in Tokyo, you know, last fall and we just, you know, met for the first time and that's usual greetings like how are you, where are you from and then just say from Prague, from Prague, right? Now, we have something like OpenStack days through the Prague, through the Europe. It would be really nice if we can have something in Prague. I will somehow find a way how to do it, right? I'm sorry, why not? So, today we are here just because what we think in Tokyo. I think it's a really good big story. That's how OpenStack works, you know, you're in one country and next thing you know you're in another continent having an amazing OpenStack day. Today we have a different kind of presentation, right? This is the keynote, first speech of the conference. So this is not too much technical because, you know, after me the guys which deploys, operates, I know amazingly fast are able to create OpenStack and other applications. So my goal here is to deliver a little bit different point of view to OpenStack. The OpenStack as a community, as a code and as a piece of art, right? Because right here in the contemporary art of contemporary gallery. Gallery of contemporary art, right? I think that OpenStack itself is also really something bigger than just code. Now and that's because of community and users and developers and everyone. So I'll let a little bit Mark Koya talk about community because he is, I think the idea is really known from beginning with OpenStack. Now, so everybody, everything about community. Travel now to the planet just to talk about how OpenStack is going to be. Yeah, thank you so much. It's just really awesome to be able to come here. And, you know, this community means so much to us. OpenStack community is incredibly global. We have tens of thousands of members of almost every country in the world. And that's really what makes OpenStack work. And it's so important to us at the Foundation. We actually brought our entire staff here today. So every employee of the OpenStack Foundation is here. I encourage you to try to get to meet the team if you have a chance. You know, we're here to help and learn more about what you want to get out of OpenStack. You know, in terms of how the community has grown and how things are starting to change, you know, one of the biggest things we're seeing is how people are moving from just considering and planning and architecting clouds to really running in production. So the largest automaker in the world runs OpenStack now. We've got the largest power company in China and the largest mobile phone companies. So it's really running in production at massive scale. And what that means is there's a new opportunity for us to think about how to run applications on these big clouds. You know, we're finally at a place where we have this global platform, dozens of public clouds, thousands of private clouds. People want to start thinking about applications, you know, and one of the things that they're doing is combining OpenStack with other technologies. So things like Kubernetes and Cloud Foundry and other application-specific kind of frameworks are really starting to see something like a lamp stack of cloud emerge. And that's really exciting. It's an exciting time. You know, some of the folks here at TCB Cloud are doing some of the most innovative work on that. We'll be seeing some really cool applications in just a little bit just to kind of show that off. But I think that's one of the biggest trends we're seeing. We're starting to do application hackathons. So David Flanders here in the front row is our foundation guy focused on app hackathons. So it's a really exciting time now that OpenStack is maturing to see what you can really do with it in terms of creating value on top. And lastly, I just want to mention that one of the biggest challenges we have is trying to help create a larger and larger group of experts that understand OpenStack, understand how to operate and how to build apps for it. So the app hackathon is one piece of that. Another is a certified OpenStack administrator we just launched at the Austin Summit a couple months ago. And so I encourage all of you to look into the certified OpenStack administrator program. We're expecting to have thousands of people take those exams just this year and it's only going to ramp up from there. So that really helps kind of bridge that talent gap. So these are some of the things we're working on at the foundation. I'd love for all of you to get involved. Yeah, great, Mark. Thank you very much. And now it's time for our pride. This is it, you know. This is the high end of OpenStack. You know, it's something what, you know, usual people, if they look at OpenStack, first they want to see is complexity, you know. Many tools, many different projects. I think it's beautiful, I don't know. Yeah, it's awesome. I agree. No, but first, you know, like, if you are first and you see something like that, first OpenStack, you know, first point of view, and you start thinking about usually you're solving some issues in your take-inside, right? For example, you're not able to be agile enough, you know, to do new products, to, you know, even design right now, you know, I think all our new market is in transition. To design new IT for the next five years is something we need to tackle. And if you look at this, it's going to be a little bit, you know, confused. But don't be confused. This is something which is already solved. And today you will see many companies, many experts, talking about how easy it is to deploy something like that and how easy it is to operate. The only thing you need to figure out is about your use case. What do you want to, you know, run? What do you want to do with OpenStack? OpenStack is, there's everything. Basically, if you want verge machines, you want containers, you want application catalogs, you want SD and software-defined storages, or you want to adopt your physical parameter data center, you are able to. It's just about your vision, what you want to do, what you want to run, how you want to run it, and that's important. As a user, the only thing you need to figure out is your vision and how and when you want to start. You know, the goal of this conference today, our OpenStack day, is to, you know, open your eyes and mind about what you are able to do. Now today, if you start working with OpenStack or any other traditional technologies besides OpenStack, usually you need one year to adopt, right? You need another year to design, and these two years everybody else are in front of you. With OpenStack, it's all these deployment tools, it's everything, which is after the big time of OpenStack, because it's not just tools for, you know, API layers, it's just something above. And all the lunch that you're talking about, Kubernetes, you know, all OpenContrail, for example, all these tools around, make your environment, make the environment for you, which is you're able to do whatever you want. And that's something that we want to present to you, you know, that's the main goal of my keynote here, that's everything that's open for you, because the only thing you need to do is just download, download, test, look at the presentation and think about it, what do you want to achieve in the next six months? That's the only thing important. You know, about this, how this is working, what's RPC you need to link, which kind of message, you know, you need, it's already done, because OpenStack is five years or more with us already, and three or four years of production in some huge companies, and that's everything solved. It's just right now. Forget this and start talking about your news cases. You can make your own ARC once you can rely on something like this to actually help you process, store and move data every app. It needs those fundamental capabilities. We finally got a really solid foundation upon which people can express themselves and create their own ARC through applications, so it's pretty exciting to be able to see the original vision of OpenStack really come into fruition all over the world. Yeah, right. And, you know, just to help you a little bit, I want to show you one use case which is not too common, right? It's a use case to bring a piece of Austin Summit, you know, OpenStack Summit in Austin, which is last month. Yeah, we had 7,800 people registered for the last OpenStack Summit. You know, for those who aren't familiar, we have summits twice a year to bring people together from all over the world, 60 plus countries attend. You know, of course Adam's there and your whole team and they did an incredible demo, so they're going to reprise it here in Prague for you guys. I hope you enjoy it. Yeah, so we just bring you a small piece of demo and a little bit different kind of use case. You know, if you talk about cloud, usually you're talking about virtual machines. And this is not a use case. Rock virtual machine is not a use case. Use cases, for example, let's measure some data and let's process them, right? So we prepare an OpenStack Day.tcpcode.eu and it's open for everyone. You can go and see, for example, how many CO2 we're producing right now in this room. So we just cover three rooms, you know, running the show here, this room, another room with boots, and another room where an evening session will be. So how are you able to measure that? That's a really cool question. It's because of OpenStack and because of the environment around OpenStack. Now that's important. APIs, SDN, right? Software defined storages. We use OpenStack sold to deploy everything. One click. Just one guy was able to do this. It's true that he spent like three hours here yesterday, but he did it along, you know, from end-to-end, so from virtual machine, from spinning virtual machine to place sensor on the walls to wire up. So you put sensors in the rooms here. Yeah, it's wireless mesh network, you know. Wow, wireless mesh network. That was him. So this is also, which is important, this is not just some visualization. It's end-to-end process of some data. You know, from beginning, when the data, you get the data and when information you took from the data, that's important. Visualizing and everything, that's important. But also, which is important, that all the data are available for you through the REST API and you are able to do whatever you want, automate through other application, share the information and it generates even more interesting information than the top of this. And from last conference, we're just adding a little bit more data so you can correlate, for example, with the traffic and our wireless network today. So even this data is available. You are able, from different sources, get a different kind of data and generate information which is available for you. And I believe the sensors are actually Raspberry Pis, is that right? Yeah, that's part of the kit. Yeah, that's funny, we're using this Raspberry Pi. And the Raspberry Pi, there's Kubernetes. So if you know something about Kubernetes, you run Kubernetes in Raspberry Pi with Kubernetes and even with SDN, which is seamlessly connected to OpenStack and it's orchestrated through OpenStack and through OpenSecSold project. And by the way, you can see on the small plate, it's like Raspberry, it's like dessert, just in the boot section, right next to the Raspberry Pi. Yeah, I don't need it, please. That is part, really, but don't need it, please. So, Marguerite, if something else would you see, describe, so something, I'll heat them up a little bit in the morning. Warm them up, yeah? And that's, you always talk about, your story about the Prague, by, you're also interested in Prague. I remember in Tokyo. Oh, right, right, right, yes. I just think the people here are amazing. Is that the story? Really, really amazing. Yeah, so, by the way, one of the things that Marguerite mentioned is that the Prague, it's a really good place to meet everyone else from OpenStack Foundation and stuff. It goes, it's everyone from Prague just prime memories, right? Yeah, it's an incredible place. This is my second trip. It's 15 years ago, the last time I came and a long time before OpenStack. So, when we started talking about how we needed to go with other OpenStack days, it was an easy choice in my mind. Yeah. So, please take a look to these, today, presentation about use cases, how to deploy, and how easy it's able to tackle. How many experts are in this room and how many experts from all kind of countries, from all around the world, just take this experience. And by the way, I invite you to the networking party in the end where the beers, wines, and some desserts will be and some small food for you. And we just prepare few hours to connect each other. So, all OpenStack staff, experts from different countries, all of them, for OpenStack will be here and you are able to connect networking and share experience. And that's the mission of OpenStack Day today. So, thank you very much. Thank you. And if I ask Altia to introduce our speaker.
