 Next, we're going to hear from another user who's using OpenStack in production and looking at the future of their cloud strategy, and they want to share some of that with us. So we have Neil Sato and Kentaro Sasaki from Rakuten. So come on out. Nice. Nice logo. All right. Okay. Anyway. So it's an honor to be here, to be in front of a great community. Today, we want to share our experience of OpenStack at Rakuten. And just to give you a heads up, we're not – we haven't really played around that much. Actually, we got it implemented in production ready. We're currently working with the site operation members to get the production system on there. And so it's – we're still at the early phase. But I was hoping that by sharing our experience of OpenStack with the people who are still considering to use OpenStack to give sort of encouragement to start working on a presentation. Okay. So let us introduce about Rakuten. For those of you who live in Japan, you might already know what we do. But for those of you who are outside of Japan, I'd just like to quickly introduce what we do. We've been providing e-commerce business for – since 1996 and slowly – rapidly expanding. So you have more of a general internet company. And we've been in the business for, like I said, 20 years or so. Now it's up to about 18,000 employees. We've got a few thousand engineers working all over the world. And what we are providing is what we call a Rakuten ecosystem. It's to provide one-stop access to a wide range of internet services. That's more of a marketing term. So starting with the e-commerce business, we expanded the other e-commerce business like travel on the right side, media portal, digital goods as well. And also recently, a lot of revenue is coming from a financial area of the service, such as credit card, banking, securities, life insurance. And we even have telecom service that we are managing right now. And domestically here in Japan, we have approximately over 100 million users or customers, we call them. And in the transaction volume, we're getting to close to 10 trillion Japanese yen. And we're not sticking just domestically here in Japan. We're actively expanding overseas. You might have heard our name before, I may not, but if you're in North America, you might have heard of a company like Buy.com or eBay. And in Europe, Price Minister in France, Play.com in UK. And these are a company that we've been acquiring in the past. Some are rebranded as a Rockton service. And we also expanded our service to e-book business by acquiring Kobo in Toronto, Canada. And there's some media business such as Vicky and Wucky are the other companies. And recently, a pretty large acquisition that we had was Viber, messaging and voice over IP service. So to support so many of these services, we as global operations have been providing a private cloud solution to the internal customers. And we started out back in 2010 using Zen as a hypervisor. And we got about 2,000 instances. We had a little glitches here and there, a lot of lack of understanding how the hyper version works. So we decided to switch to VMware. This was in 2012. And this actually came out to be pretty good. It was very stable. We didn't see major downtime with a VMware setup. Now I think the slide says 20,000, but I think we're all the way up to about 21,000 instances right now. Now this year, actually, we started digging more into OpenStack. And this year, we got the OpenStack setup. I'm going to pass the microphone to Kentaro, who will explain more about the technical aspect of it. So let me explain how OpenStack is working and what we expect to do by using OpenStack. Anyway, so as you can see, something red are the servers, which run OpenStack services and stuff in green. And the circle shape are the other servers, which do not depend on the OpenStack. So the only one or two services run on each server, so it means that we are using much more servers than a sort of architecture example, what we assume as the standard design. And all of our compute server has local SSDs and run KVM 2.0. And we have a huge real FS cluster for grounds back end. This is an internal developed open source object storage, which has Amazon S3 API. And actually, we don't use the layer 3 networking, so the driver of what we use is run plus open free switch. And since there is still under consideration so far. We have three regions and five of it is on. So basically, we have a sort of environment, which are development, staging, and production. So we define them as the region. So actually, we have not introduced a block storage service, but we also have an experience about the traditional enterprise storage. So we're going to introduce a cylinder by using some sort of the storage. And also, we have not began something about the implement network management. So we're going to implement something like this stuff. And full automation is a very important strategy for us. So we definitely need to be working on using the API. So I believe that using the API is the only neat thing to do in terms of using the open stack. So the next hero is going to sum up. Go ahead. So we really love open stack, although we've been just scratching the surface of what open stack is capable of. But I think the important part about committing to open stack is about contribution, including Ken Taro and the other teams, my other members in my team, are contributing to the open stack community. And I think I don't like to use the word like responsibility or obligation, but I think it's a philosophy of open source project is to get involved and be part of the community. I think I've been in this business and I've also contributed an open stack, I mean, open source project and I really enjoyed it. And I see a lot of future in this movement. So if you're looking forward to working on open stack here in Tokyo, we're hiring and I'm supposed to throw that in because HR told me to do so. Or with Jackson, right? Yeah. Anyway, so thanks a lot. We're looking forward to working with everybody in this community. Thank you very much. That was amazing. You know, I just realized that the Japanese travel book I checked out of the library was a little out of date because I'm the only one wearing a suit. So you got to do your research, people.
