 Hello everyone. My name is Aishah. I work for ULITID stack. Today I will give you an introduction and a demo of the ULITID stack OS. A little bit about us. ULITID stack is the first dedicated open-stack company in China. We have a bunch of top and cool engineering from the infrastructure team of the Internet companies and also from the open source world. ULITID stack OS is an open-stack distribution. It is beautiful private cloud. So why do we need another open-stack distribution? Open-stack is powerful. This is great but it is too complicated for most users to run them. And in the open-stack system we have a bunch of related technologies for your database, for your storage, for your network. Usually users can just cannot run them very well. So can we have a cloud operating system which is as easy as your personal OS or your mobile OS. With this in mind we have the design goal of the ULITID stack OS. You can read it here that is any IT staff can deploy and maintain a private open-stack cloud without any services or trainings or even without the knowledge of open-stack. This is how we deploy one single machine. You have one machine, you have one OS and you have a council for that. How can we deploy tens or hundreds of machines? Can we also have one single operating system for it and have one single council for that? So here with ULITID stack OS all you need is an USB disk. The deployment of your OS is extremely easy. You do not have to hundreds of pages to read before you can deploy your cloud OS. What you need is three steps. You just need to prepare a v-line for your cloud and put your server with your USB disk. The installer will install all the packages and the dependencies for you and configure for it. After that you can log into your OS web console and at this point you actually can already use a cloud already. If you want to add more physical servers to your cloud you can open the console and install physical server. If you boot physical servers through the network it will show up there and you can press install to install the physical servers. All the installation and configurations will done automatically. Here we have prepared a video demo for the installation process. Let's check it out. So we only have one page of manual for the installation. Just three steps. Here we are booting from the USB disk installing, select the network and you just need one input the network address you want to use and the package is installing. Right now we are rebooting to the hard disk. The popular module is running. The popular module is doing all the hard work to install different components of the system. For example, safe, my circle, key store, etc. Now we have the web console available now. We can tap your username and the password and continue. Here are the overview of the network. You can adjust the physical server and the virtual machine server IP pool. You can verify if the network works for you by verifying network. After that all you have to do is grab a cup of coffee and wait for the installation process to be done. Now we can log into the console to use the cloud. Next we'll show you how to add physical servers to your cloud. Here we have a module to add more physical servers. This shows the current server available and this shows the different system info for your server. If you put a machine through a network it will show up here. And you can see we already added the second machine into the cloud and the installation process is ongoing. Okay. This is the installation. I will do another live demo of the system. We have prepared the cloud and this cloud is operating in Beijing. We are already in Beijing. This is the overview of the system. You can see the CPU information, IP information, RAM, instances, etc. Here we can create instances. Let's create a Windows 7 and we want to create eight instances. Okay. We are creating. It should be fast because we integrate deeply with the safe cluster. This way we do not have to copy data back and forth from the glans to the Lova. We just can directly boot the servers from the safe cluster. So it will be faster. As far as I know we should be the first vendor to integrate the safe into the Lova. Open the console. Okay. The Windows is booting. This is our broad storage. They also integrated with the safe cluster. We can create volumes here. We have three. Yeah. It's creative. We can also take snapshots. Here are the images available into the system. And here we can add security groups and key pairs. I also want to mention that our monitor system is based on a denominator. But we extended it with a lot of works. We added more metrics. For example, we integrate the safe monitoring in it. For example, we have capacity of the OSD in the safe system. And the health status of the system. Read bandwidth, read operations, et cetera. Also we create a tool to generate reports. We first need to create a widget. A widget is used to define what data we want to use and how we can display the data. The system is running for a while. So there might be a lot of data. It's loading. Okay. For example, if I want to check the hardware and to save you information, I want to check the context switch. The second node and the master load. We can check preview, which context switch. And we can save it. Okay. The widget is created. Based on the widget, we can create a report. Here is the widget we just created. And report says one. We can preview it and save it. This is the report we just created. And this is the context switch of the server. Just to give you an idea how this reporting system is working. You can add whatever metric you want to create a magic chart. And this is the storage. You can upload, download files here. And this switch back to the admin overview. This is the overview of the system. The number of virtual machines, number of physical servers, and the status of the IO network disk information. Here, we can show the current physical servers in the system. You can add more physical servers. Here, if you boot a server with PXE, the server will show it here automatically. You just press install here. We cannot see it right now. And it will install it automatically for you. We are loading. Also, we can do since next migration here. Let's say if I want to migrate this machine to another machine. Currently, it's on the second physical machine. I want to migrate to the master load. The migration is in progress. Check if it's down, okay? Okay, so the migration is done. This interface is our, here we can add projects or users or update the user information here. This is our interface for the logs. We integrated all the logs into one place. We can view various logs. For example, for Nova, for Kistore, and etc. We integrated them. We can, we can type a keyword we want to search. We can also download the log. Okay, I guess this is all for me. Any questions? Okay, thanks.
