 I'm sorry, my Chinese is very bad. I'd like to remind everyone to please turn off your cell phones. My name is David Greenberg, and I'm one of the co-chairs of MesosCon. We have simultaneous translation devices available outside in the hallway. In Channel 1 is in Chinese, and in Channel 2 is in English. And you can change your ID card for a translation device if you need one. Fan Yu Shi Mei, zai, qian jing, qing, ping jeng, jian, ning jiu. And don't forget to come to our reception tonight. It'll be outside in the foyer. And so there, we can socialize and network. And that'll be tonight after the conference, just outside there. There is a slide that comes next, which I was in control of. I would like to thank our diamond sponsors, IBM and Mesosphere, who are our number one contributors to Mesos. So thank you, IBM. Thank you, Mesosphere. I'd also like to thank our platinum sponsor, Shuren Yun, and our gold sponsors, Huawei and NCS. I would like to invite Dr. Xie Dong, the vice president of the China Systems Lab at IBM, and Ben Hindman, the founder and chief architect of Mesosphere and the creator of Mesos at Berkeley to the stage for our opening address. Thank you, Dave. I'm very happy to be here at this conference in Hangzhou. Hangzhou has both delicious food and beautiful scenery. And it's still a city with high-speed development. I'm very confident that there will be a lot of development. But we'll stop here for a while and talk about Mesos. As IBM, we are very happy to be here at this conference. Perhaps you all know that IBM has been established in the open-source community like Linux. In fact, IBM started to support Linux in 1998 and then in 1999, they established Linux and then the center to support the development of Linux in the community. After that, for so many years, IBM has invested a lot in Linux and in the open-source community. Up to now, IBM has more than 200 products. It's based on the open-source project. And then there's IBM once put over 500 patents in the open-source community. And now, there are more than 1,000 developers in the open-source community. They are always the developers of the open-source project. As you can see, in all these years, there are a lot of products in the open-source community. There are a lot of projects that support open-source. They have the external server, then the open-source data, then the large data, then the cloud data, and then the hyperlider, blockchain, and open-power, etc. In this process, IBM is not only the user of the open-source project, but also the user of the open-source project, and so on. In this process, it is especially said that IBM has provided a lot of projects in the open-source community. We can see that in the success of a lot of open-source projects, not only rely on the success of each open-source project, but also on the contribution of these technicians. It also relies on the hard work of a lot of their success. At that time, we believe that IBM has played such a role. We know that a lot of users are using open-source projects that are facing some difficulties in the selection of hard work, and long-term use of technical support. In this way, they need a partner. They need a company like IBM to help them use the open-source project. Now, we are very happy. We have an important investment in a project like MESOS. When we are at the scene, there are a lot of technical staff from IBM. I hope that we can all come together to discuss how to use MESOS in a common way, its growth and prosperity. Thank you. Next, I would like to invite the founder and chief actor Ben. Ben, please. All right. Good morning, everyone. Give me just a sec. I just have a couple of minutes with you all. All right. Everyone can hear me? That's good. Just a couple of minutes with you all. Where I wanted to share a little bit about the updates about the Apache MESOS project in the community. Recently, we ran a survey, and I collected some of the information, in fact, some of the slides from that survey. MESOS continues to grow quite a bit. This last year, we have 52 MESOS MIPS around the world. We've had three MESOS cons. This is the third MESOS con this year, and this is our first MESOS con in China, and that's very, very exciting. We've been growing the number of contributors quite a bit, which has been fantastic. I'm going to talk about that in just a second. So when we first came out, a handful of us came out early, and we went and did a meet-up out in Beijing, and that was a ton of fun. So I just wanted to capture some photos here. Here's a photo of the meet-up. It was really great to see that there really is a MESOS community here in China already that is really growing on its own. I captured a couple of the slides from Dubang's talk, where I was talking about how they're using MESOS pretty extensively, which is really cool to see. So as I mentioned, we've been adding the number of contributors, and there's three new committers that I really wanted to announce. These three new committers are actually all from China, and I'm pretty sure they're all here in their room today as well. So if they could stand up, those three newists, Qian, Hausdens, and Guangya, if you guys could stand up. You know, I think one of the most fun parts about being involved in helping to grow an open-source project is when you get to meet with and work with people from the community. And today was the first time I got to meet at this Hausdens, and it was really fun to get to meet them for the first time. So great to see the contributions from China. It's very cool. MESOS is being used in a variety of places. This is just kind of, again, some of the stats that I'd taken from the survey. What I think is really impressive about this is that only half of the MESOS users out there are just tech companies. Or said another way, half of the MESOS users are not first and foremost tech companies or digital companies. They're companies in other areas of the industry that are actually able to leverage the technology for doing really interesting things. You'll actually hear at this conference from folks in the tech world, the software world. You'll hear from Uber, you'll hear from Adobe, you'll hear from others as well. On the banking finance side, you'll actually hear from Commonwealth Bank. And on the telecom side, a little later this morning, you're gonna hear from China Unicom. So it's really exciting to see that not just around, around the world, but also here at MESOS on China, we're really getting that variability of the industry. One of the other really interesting things about how MESOS is being used today is it's really being used not just on the cloud or not just on-prem, but across all these different places. A majority of organizations are using MESOS on-prem, but there's quite a few that are actually using on hybrid. You know, we've kind of all known this as part of the MESOS project, but one of the things that we're really excited about is hybrid cloud and multi-cloud. I really think that that's the future of where the MESOS project is going and what we're focusing on. And there's a talk later today from the Adobe guys about how they're taking MESOS to multi-cloud. And there's a lot of work that's actually happening in the community right now around this. There's a federation working group that's meeting every two weeks on Tuesday morning. You can find out more about that at this MESOS Jira as well as if you check out Slack, there's a channel where there's a lot of work that's happening there. And I'm really excited about what's in store in the future for multi-cloud and hybrid cloud for MESOS. One of the other really interesting things that came out of the survey is the kinds of applications that people are running on top of MESOS. Majority containers, microservices, but still quite a few data services and analytics. One of the things that I was especially interesting to take away from the survey though was that most of our users are running containers in production, which is to say that they're using MESOS to run their containers today in production. 62% is actually a really big number compared to the industry averages of what people are actually running in production when it comes to containers. And I think one of the reasons for that is because MESOS has a really storied history when it comes to containerization. It's really been a pioneering containerization, doing containers before Docker was really a thing for a long time. We used to have this thing that we called the MESOS containerizer, that now we call the unified containerizer. And the MESOS containerizer had really innovated at the very beginning. One of the things that it did that we were always really proud of is that with the MESOS containerizer, you could reboot a MESOS agent and any of the containers you've previously had run will just keep running. That's now becoming a standard and anybody who's launching containers have to have a feature like that. You can hear more about the MESOS containerizer now, what we call the unified containerizer as a talk tomorrow. You also, though, can hear about some of the new work that we're doing in containerization during the keynote tomorrow morning. There's a presentation about this new primitive we introduced called nested containerization, which is, again, us taking the concepts of containerization and pushing it even farther. This stuff's really cool, the nested containerization stuff. I won't go into too much detail now, you'll hear more tomorrow. Related to that, we're also doing a bunch of future work around being able to attach to containers, debug containers, using this nested containerization primitive. So please check that stuff out. Okay, another area that I found really interesting in the survey was about the kinds of different workloads that people were actually running on top of MESOS. I just kinda wanted to zoom in on big data because big data ends up being one of the things that's running a really big way on top of MESOS. Spark, Kafka, Elasticsearch, Cassandra, Hadoop, so forth and so on. And one of the things that's really exciting for us about that is it's really this advent of the future, which is multi-tenancy is key. In fact, one of the stats that we got was the average user's running three or more frameworks on top of MESOS, so three or more big data or different kinds of workloads at the same time. So multi-tenancy really is the future of where everyone's going in the container orchestration and the resource management space. There's one talk, one of the last talks of the day tomorrow by our friends at Uber is gonna be talking about how they're extending MESOS to run multiple frameworks. And there's a lot that's happening here in the community right now that's all about the new primitives, new abstractions we're gonna be building into MESOS to support multi-tenancy. So that's really exciting, lots of fun things here. A bunch of this is actually work that we've been doing with our colleagues and our new committers from China. So it's especially exciting to be here and working with them in person on that. Okay, one last information that we got from the survey that I really liked was why people were picking MESOS. And the couple of the big ones that popped up was scale. They knew that they could run it at scale in their organizations. Product maturity, it's been running for a very long time in a bunch of organizations. It had features like high availability, fault tolerance and all these things were matured and people felt that they could trust this technology for in their environments. But one of the things that I really took out of this that I thought was so interesting was while this is all true and the product is mature and we can run at scale, we continue to innovate quite a bit. We continue to change all the time. There's a lot of things that we're introducing all the time. And I think that's one of the critical things of open source projects is when they get mature they continue to change. They continue to change in a way where organizations can benefit from the changes. So there is a talk later today that I think is interesting. Talking about getting rid of Zookeeper. It's one of those things that's really stable in Mesos. We want to be able to allow people to use other technologies like at CD. There's lots of other interesting work. I could have called out a bunch of them. I only called out one which is restartable tasks. It's work that's being driven by Apple where they're trying to introduce this to make running some of the stateful services that they have on top of Mesos work even better. Again, you can check out a lot more at the roadmap. So that was all I had. Just a couple of quick notes. I'm so excited to be here at Mesos Con China. This is, I know it's especially exciting for the Mesos Con community here. And I'm hoping that everybody has a lot of fun the next two days. Thank you.
