 Hi, good morning everyone. My name is Bart Liu. I'm from Tencent Cloud. It's a great honor for me to be here to share with you the experience we accumulated in terms of cloud native. For Tencent Cloud, for Tencent, well actually for the total server, there's more than one million units. And also for the containers number and also functions number is billions, it's at billions. So such an immense number to support QQ and also gaming, Tencent gaming and also WeChat for their stable operation. And during the journey we have accumulated a lot of best practice and therefore we have the Tencent Cloud container platform and it can be used for government, for financial industry and also for some traditional manufacturing industry. So with Gevanitis, it is more and more accepted by the users. We also have officially built the enterprise container cloud platform. This is called TKE Enterprise. The TKE can help other users to privatize their containers. And the fundamental layers is in accordance with the public cloud of Tencent. And this will help with the hybrid cloud management and also inside Tencent. We also work on the Gevanitis practices and the development. And also with the management, we can make it with smaller gradually and more controllable with the online and offline operation. We also can help with the efficiency of the resources utilization. Here I want to talk about Tencent Cloud TKE Mesh. With the development of the TKE Mesh, the control and management requirement is getting higher. The TKE Mesh is from Institute and it is seamlessly connected with Tencent Cloud. And once you launch this TKE Mesh, you will get the harmonized service. And this also will be used in the hybrid cloud and the edge computing in the future. So with this efficiency, we also hope to constantly decrease the compromising of the performance from the Mesh. Like some of the workloads will be put into the smart link. And this can help to reduce the consumption of the performance. The serverless is a most popular computing platform with the highest growth rate from 2018 to now in Tencent. Its growth rate is very high. But it also has some short weakness like the event-based development path and mechanism is not what the developer got used to. And in certain scenarios, its performance is not as good as the others. Its launching, its start is also kind of slow. So we hope that with the HTTP function within 5 minutes other users can develop a web service. And the language it supports includes the Java, Loft.js and these are the common ones. These can be seamlessly transferred to other service platforms. And in the future, more language will be used in this platform. And last but not least, we will have the complete serverless solution including the monitoring and debugging and alerts. And we have the virtualization to solve the issue with the security and isolation. And for the performance and experience, we also hope to keep it in the top position in this industry and to have the real-time and smooth experiences provided to other users. Last year, we worked with WeChat and made the mini-programme cloud service platform. This service is very good. After one year, we have seen very quick development. So currently, there are 160,000 developers are using the mini-programme service. And the users will pay more attention to their own logic code and the development cost is smaller. And now, we are constantly improving the experience. So in the future, we believe that there will be more support given to other developers. So in the future, when you are developing the mini-programme in WeChat, the first thing you can think of is our service list service from Tencent. So we hope that we can bring you with more efficient and smooth experiences. And this is our DevOps service, which is a one-stop service. We look at the deployment, the efficiency, and the whole system layout. Last year, we invested in coding. And in this year, we will have the coding 2.0 launched. It includes the software development from the beginning to the delivery. And including the program management as a code management. Thank you very much.
