 Hello, hello. Let's begin. Hello, Staker. I'm Vincent. Center for your coming for my speech. At first, I want to introduce our company. Take a few minutes. Because we come from China, it's a long trip. Our company is H3C. We are IT company. Absolutely, we are IT company. So, we can provide the software and the hardware that data center used. The software, such as cloud management platform, based on OpenState, that's why we're here. And the virtualization software, based on KVM, and we also provide the SDN controller and the data center monitoring the software. And we also can provide the Docker and the pass as big data software. What about the hardware? We can provide the network device and server storage security device. And all the product is developed by R&D. So, we can integrate those software and hardware very well. And I think it's our biggest advantages is we can provide the cloud computing a total solution for customers. And up to now, we also had more than 300 customers in China. So, I think 300 is a very amazing number for every OpenState company. And our business is covering the governments enterprise, health, media, education and the other industries. And today, I will show you our special case. It's about health cloud. It's how we use the multi-level cloud to build the health cloud for the Henan province. Henan province is in China. He has the most population in China, yes. My speech includes four in three parts. The first, we'll talk about the project background and where we'll talk about the customer's requirements. And the second, and this is our solution to show how we satisfy the customer's requirements. And the third is what's the benefit that cloud brings to the customers? Yes, there's three parts. The first is the project background. As I said, I will show you the Henan province health cloud. And there are two keywords here. The Henan province, the two is health cloud. And the first, the Henan province, there is 34 provinces in China. Henan province is one of them. It's in the central of China. And they have 18 cities. And this number is where we'll use after. And the Henan province has China's most population province. There are more than 100 billion people there. So China is as large as the USA. So some are real as a medical condition and the medical level is not very well. So the government wants to build a health cloud to improve the people's medical condition. And the purpose of the health cloud, the government wants to establish the residence health record system and the primary health service system, public health service system, and the other health application for the 100 million people to improve their medical condition and promote the medical level. The government wants to use the computer, the cloud computing technology to run this application. In the meantime, they also want to innovate the mass of the management and the way of resource delivery. So we will build the Henan province health cloud. And what's the customer's request for? I think this sixth point is important. As I said, there are 18 cities in Henan province. Our customers want to establish one man cloud plan for and the cloud plan for the 18 cities. And the requirements is unified management and orchestration. So it's important. There's one unified portal where we can manage all the data centers. And below these requirements, we also develop unified identity or authentication control. In China, most of the behavior must be workflow. And the people will apply and the government will approve and they will apply the teaching. So the workflow engine is necessary. And we also will provide the higher availability for the different, for example, for the management plan for the backup, also sending auto-scale and self-healing. And the last requirement is also metric operation. Okay. We know how the Henan province health cloud begins and what's the customer's requirements. And there are certain parts where we will have a solution. Our solution has this lead. It's our general idea. I think we will also satisfy the customer's requirement from this point. And I think all over the world and the top of this is critical. It's very well made, geographically deposed and logical unified. Yes, we know the 19th center is located in a different area. And we will build a cloud to manage them as one cloud, as one data center. So we sleep two level, two level cloud. One is a province level cloud and the other is a city level cloud. And the different level clouds have different functions. For example, the province level cloud focuses on operation and management. They will... The province level cloud is charged for resource schedule and unified. And he also provides the resource for the other data center. For example, for the DR center, for the DR center, and the city level cloud focuses on service delivery. And he provides the application, provides the IT resource to nearby. And this layer, we will have the unified portal to management or the device includes the software and the hardware. And under this layer is we will help our customers to build a business focused maintenance system to help them to maintain the cloud very well. Yes, that's our general idea. And this layer is our multi-layered cloud architecture. We can see from this picture there is one province level cloud and that means 18 city level cloud and they have a different function. Different function. We're using the open-stack multi-raging solution to serve the multi-data center management. Yeah. So we can manage 19 cloud data center. Yes. Data center through the unified portal. It's just one portal. And the other administrators are looking at this one portal to operate what the data center belongs to them. Yes. And the resource will be transferred from the Pro-Ince level cloud to the city level cloud. Yes. When the Pro-Ince is as a backup center for the city level cloud, the city level cloud data center, they will never to build a backup center by each one. So they will backup to the Pro-Ince level center. And I think it's reduced the cost to build for every city level cloud to build a backup center. So even the city level center, length of the resource, a run out of the resource, they will apply the Pro-Ince level cloud resource to run their application. So we can implement the resource transfer between the different data centers. And this is a unified identity authentication. And as I said, we have only one portal and we have so many different operating groups. So we can have the unified identity authentication. And before the health cloud, without the user, the LDAP exists for a long time. So the crystal must be integrated with LDAP. So we can implement the identity unified authentication. And when the Pro-Ince cloud plan for the crystal crashed, and the city's crystal well communicates with LDAP to complete the loading. Yes, that's a unified identity authentication. And the physical and the op, that is the Chinese customers' requirements. Just the cloud computing plan for management plan for well adapts the organization that customers have. Yes, so there is an organization about this, our government's customers. And they are computing well, give the different users and the different other reads. Yes, for the author reads. And this is a unified resource or construction. Now this part I will show you a demo on how we orchestrate or the resource includes the software and the hardware. It's a web set. So this is what space we can... This is a VDC, the virtual data center. So on the left corner, the right corner and we can see the service load. And this is a firewall. It's a web router. And it's subnet, load balance, storage, and this virtual machine. And there's other application. We can track what we need on the web base. Let me show you. If I need the subnet, I will check this and... Yes. And this I joined load balance. And I choose what's his performance and it's the basic information. Yes. And next I will check the VM and the virtual machine. Yes, we can... Yes, choose what's the operation system and the memory, CPU and the disk. And his name is password. Yes. And we also can... Yes, it's a VDC. And just be the data cluster. It's for bare metal. Yes, we can deploy the bare metal software. And this is a program. Yes, we also can integrate it with the program to provide the program virtual machine. So, when we... It's a draft. It's not real to Confid. And once I click the deployed, so all the configuration will... will deploy on the device automatically. It means success. And all the... Confid... It's no need to confid the device. Just compute the cloud management plan to do this. Yes. Okay, and customize workflow and we also have the workflow engine and we also can... It's a... Our typical... It's a three-level. It's an end user, terminal administrator, cloud administrator. And when the end user wants to use some cloud resource, just as a firewall or virtual machine, they will apply on the web. And the terminal... The talent administrator and the cloud administrator approve the application. After this, our resource will deploy automatically. So, it's the customized workflow. And this is... This is an interesting function in cloud. It's auto scale. It's auto scale. And we know that some web... web application has... is regular. For sometimes one day, one month is a certain day that we will have a large access, a large number of access. When the large... When the large number of access come and the... the application will crash in the traditional IT. But we use our cloud management plan for web auto-scaling for this application. So, at first, our cloud plan for... management plan for web... monitoring the application, his CPU memory, or the connection number. So, when we'll set some... chance hold, the chance hold, when the... when the large number of the... the access happened, when the cloud management plan for... we are monitoring this, and he will... and it will... when the... when the... reached the chance hold, the cloud management plan for... will create new VM and for the application and add it... add the new VM to the load balance to... to... and to make the workflow shared. Yes. So, we can keep every... application health. Yes, health. And once the workflow is done, the resource will be released. Yes. So, all the... all the behavior is... is automatic. And we also built the... application monitoring, and it's just kind of... monitoring the... the application's CPU memory and their... the hardware performance to help the administrator to... to know how the... how the application run. Yes. And we... and we also kind of showed the... application top. Yes. It's... I mean, the admin... administrator to know how the... application is. Yeah. Okay, the... okay, the third part is benefits the cloud bring to the customers. So, this is a screen shot from the... the production environment. This... this map is... the Hunan province has maps. And every color block is... means different city. And every... the number on the... different color... block is... means... the... cloud... the situation. Our CMP will give the mark about every... city-level cloud. And as administrator will know it's how the... every... every... city center are operating. Yes. If they found some... some mark is very low. It's very low. They will... they will check it, yes. And the... the... the health cloud bring to the customers as in the four... the four points. Simple eye... resource operates and maintenance resource. And the second is the resource... utilization improvement. And the project runs rapidly. There's a way... we have... finished the... the 19... the center implement... just... just close the... three months. Three months to finish this. It's a big... it's a big project and we will... have a long... long trip to... to... to drive this. And the high ability of the health business to... to protect the... the... the... the... the application health, yes. And the final... I think the... Hernan... Hernan province health cloud has... on life for more or less one years. It helps... 100 million people to improve their... medical condition. So I think it's... proud of... proud of us. Yes. Thank you. That's my topic. Have any questions? Okay. That's all. Thank you very much.
