 Hi everyone, I'm Shintaro Mizuno from Entity Software Innovation Center, one of the R&D division in Entity Group. And my name is Toshikazu Ichikawa, also working for Entity Software Innovation Center. And thanks for this opportunity to introduce ourselves and some activities around OpenStack in Entity Group. So Entity R&D has a mission to evaluate and design OpenStack to be used in various Entity Group companies, including Entity Communications, Entity East, West, and Entity Docomo, and other Entity Business companies as well. So there are various implementation and use cases in Entity Group. So Toshikazu, can you explain some of the major use cases in Entity Group that you can explain to the audience? Okay. Shintaro, we have mainly three deployment in the production today. First one is Entity Resonant, which is our web portal company providing web service called GU. Second one is Entity Docomo email system providing email service. We are using OpenStack as a backend of it. And the third thing is Entity Communications deployment for the public cloud services. Thanks. We also have our own internal R&D cloud for our researchers to use so that we ourselves are the user and also the developer as well. So Entity Group is a big user of OpenStack and thanks for the foundation to award us as a super user. Yesterday was a very fantastic moment for us. But at the same time, we're also a big contributor to the OpenStack community as well. So Toshikazu, can you give us some numbers that we have been contributing around four years since its launch in bear release? Okay. So I'm going to give a deep overview about Entity Resonant use cases. They are portal sites that generate more than one billion page views per month. As a backend, we are using OpenStack, including Swift, Nova, Granz, Keystone Horizon, and Neutral. We deployed more than 400 hypervisors and more than 1,800 virtual servers are already running in the production. More than one year in a stable and more than 80 service is on top of the OpenStack. Okay, great. So behind those use cases, we have more engineers contributing to the community. So can you give us their efforts in the community activity? Okay. So we have a lot of developers, including Entity R&D and even the other operating company. We have been ever committed to the OpenStack community with 64 developers, engineers, have ever contributed. It's great. So we are a big contributor. We are putting more efforts to the community. We are pleased to use OpenStack in many different more use cases, and we have more requirements that we need to upstream to the community. So do you have any specific areas that we want to contribute to the community for probably the next few cycles? Okay. I'm going to pick up two large topics. One is return request ID log mapping. It's a kind of request proposal from an operator's viewpoint. Today it's hard to analyze OpenStack logging for the troubleshooting, especially when one request goes through multiple components. It's hard to track one customer's request. Then we are proposing logging the request ID in connection with a single customer's request. That is already approved by the OpenStack close project spec, and we are now working on the implement in Oslo library and major components. Also, we are working on the networking perspective. We are deeply contributing to the neutron project. We are proposing features such as availability zone support from Neutron and even distributed virtual router with a Linux bridge. We want to enforce much capability to the Neutron project. Thanks. NTT Group has been a big contributor to OpenStack community and as well as the big user of OpenStack and a big fan of OpenStack as well. We will keep doing our contributing and we would love to share our experiences. We have various sessions in this summit. If you missed it, please check the website for the video. We have around more than 10 sessions from NTT Group to share our experiences. So please check on the video and please also join the session if you are here in Tokyo. We are expecting your feedback and we thank you for this great opportunity to be on the screen of this video. We hope to be in touch with all the community members and be a part of this big wonderful community. Thank you. We are going to keep contributing. Thank you very much for this great opportunity. Bye.
