 Good afternoon everyone, I'm Chang Bo Guo and this is my college, Ho Ming Wang. We are from EZ Stack. Today, we will introduce the ESCast version 2. One platform for environmental, VM, and container. So, let's see the agenda. First, I will introduce EZ Stack briefly. Let's see what we did in ESCast version 1. And what's the update in ESCast version 2. And at last, we will do a demo. EZ Stack is a leading OpenStack cloud platform and service provider. Two days ago, EZ Stack was accepted as a good member of OpenStack Foundation. Software engineers from EZ Stack have been contributing OpenStack from ESC House. So, in the last release, Mintaka, EZ Stack is one of the top contributors. And in the same release, two of our engineers were nominated and approved as project car reviewer. We provide cloud development and service for more than 10, more than 100 underpriced customers, including state-grade China Telecom, the novel post-saving bank of China, Shi Feng Group, TCL, and Tsinghua University. You can find more customer use kits from our official website. So, what is ESCast? It is a self-service control platform. You can spring up dedicated OpenStack cloud units. It provides more flexible service and better control for your cloud environment with stronger security. It provides dedicated host, isolated networking, active storage. So, let's see, this is architecture. In this picture, there are three areas, the center and left and right. Each area includes resources, including network, host, and storage. In the center areas, there are shared resources. All users from any domain can access them. But in the left and right, there are specific dedicated resources. This is the only access for specific domain. So, if you want high performance and stronger security, you can add domain-specific dedicated resources to the domain user. This is the ESCast UI. In the left, there are two panels, the public and the dedicated cloud. See, as a domain administrator, you can add three types of dedicated resources. It includes compute, storage, and networking. Each type has different types. I mean, also the different flavors. For example, for the compute resources, you can add more CPU cores and RAMs. When you add the resources to specific domain, then you can see what we have and what's available for specific domain. In this web, there are three type resources, the CPU. You can see there are only two host with small type, and the storage results with type HDDD, and the networking. The difference between the normal OpenStack and the dedicated cloud, the difference is the user can put a test in a normal OpenStack environment or dedicated cloud. We demoed ESCast version Y in the Tokyo Summit. So if you need more information, you can visit the link. So what's the update in ESCast version 2? First, it is our data center operating system based on OpenStack. It can orchestrate your cloud-native application, your frameworks, like missiles, coolness, and swarm. It's also a unified platform for container cluster and application creating and monitoring. My colleague, Homing, will introduce more details and demo it. It's your turn, Homing. Okay. Good to often know everyone. I'm Homing from ESCast. In the next, I will give you some details of our ESCast version 2, and I will do a live demo. First, we can see the architecture of the ESCast version 2. As Jonathan said in yesterday's keynote, OpenStack is an integrated OpenStack. It's an integrated engine for all the open source projects. OpenStack is for infrastructure primitives. It uses projects like NOVA, Glance, Neutron, Sindor, Crystal, or Swift to manage infrastructure in your data center. Based on that, some application primitives projects like HIT, Sahara, and Magnum can provide the application power to the end user. And on top of that, we OpenStack also embrace the cloud native frameworks like Kubernetes, Smithers, and so on. And demo time. And I will demo how ESCast version 2 to quickly provision docker cluster and applications. Here we go. First, we look in. This is the overview page of the cloud admin. And we can change to the project admin overview. Here, we can see the resource quota usage of this tenant. And on the above, I can see the cluster monitor information and the application running in the cluster. This is the cluster CPU usage. And this is the cluster run. Running nodes in this cluster. And this is running applications. Right now, I will create container clusters and applications. First, create a cluster. Hello, Austin. For demo, we only create one master node and one slave node. And we can see the cluster is created in process. From the instance list, we can see the machine is being created. And the container cluster is being configured in the background. This may take two or three minutes to create in process. Because it needed some time to download the images. And the network speed is not fast enough. Just wait a minute. Let's check. Okay, we can see the two VM is all created. And the cluster is being ready in a moment. Okay, we can see the new cluster is created complete. And then I will create two applications based on this cluster. For demo, I will create WordPress application. And it contained by two applications. One is My Circle and the other is WordPress. First, My Circle. And we choose which cluster to run this application. And we choose the new cluster. Hello, Austin. Image name. And we add a monopoint. We increase the CPU and memory. And My Circle through a spot is 3, 3, 2, 8, 2, 6, TCP. And I will set the My Circle password. Okay. You are network, maybe the network is done. I can't operation the horizon. We also record the demo movie. So we can see the record, the demo record. This is the application created. First, My Circle, image washer, My Circle. And we can say My Circle is being created and running. Next, we create WordPress image, CPU memory. And set the environment parameters. And we can say both WordPress and My Circle is running on the clusters. And then we can say the two cluster is in the all wheel page. We can say the cluster usage and the application usage data. And then we look into the WordPress. And the new WordPress is running in the container cluster. Okay. Sorry. Okay. This is all the demo. Yes. What is your name? Yes. In the Austin Summit, we create two customer case studies from Lenovo and the state-grade coverage of China. So if you need more information, please find us in the booth A21. Thanks, everyone. Thank you.
