 I'm Xin Zhang, VP of Volcano Engine at ByteDance. I feel very honored to be here to present to you about what we do, why and how we approach it. By August 2020, Douyin, the most popular short video content platform in China, has reached 600 million DAU, or daily active user, and the MAU, or monthly active user of all ByteDance apps, has reached 1.5 billion globally. We're talking about the rocket's big growth here. Given the huge amount of diversified content and information our platforms carry, and for Douyin's video content aggregation, editing, analysis, and recommendation, these are highly relevant with real-time distributed storage, computing capacity, and orchestration. It has never been an easy task to manage them all at such scalability. Over time, we have generated a coherent framework that works from the infrastructure operating system level to mid-platform, then end-to-end suites for growth that can also be paired with various industrialized solutions. Such capabilities and methodology have been quickly serving the needs of various business lines or units in ByteDance over the past eight years. As you know, Total, Douyin were the early ones, and then Data, Mobile, etc. Now, all these come in combo in Volcano Engine. We call this coherent framework one-set, and with these suites and capabilities, Volcano Engine has boosted ByteDance growth in the past. In a similar manner, we're thinking we can help other companies or enterprises to grow by using the same set of core technologies and best practices. That's the essence and the mission of Volcano Engine. As mentioned, during the years we have built all these phenomenal apps like Douyin, we have been faced with the growth of millions of users and content. We need Cloud Native in production. We're running tons of containers, writing microservices, dynamic orchestration, coupling and decoupling services, handling persistent data, and the list can go on and on. Lots of times we need to go against the traditional go-to habits of building apps from static and monolithic to achieve scalability in a Cloud Native way. From our experience, Cloud Native in production is not only about shifting a single app or its dataset up to the Cloud, or automating certain tasks or integration. It's about seriously having the whole business to the Cloud Native level, a complete transformation that involves technical, procedural, and sometimes even organizational challenges. Volcano Engine has been going the Cloud Native way since very early on. Built on the half million node scale we're dealing with, we gained experience and had valuable and vital lessons, which could be also useful to companies and developers in the community who are going through the same Cloud Native transformation and confusion. We're interested to share and exchange this information and insight with the community friends. And at the same time, we'd love to continue to contribute to the open source projects, including Kubernetes, Kubeflow, not only the Cloud Native orchestration projects, but also those relevant with data driven goals. As a debut on the KubeCon stage, today is a very important milestone for Volcano Engine to present its Cloud Native story. We hope to connect with every one of you in the community to inspire creativity and enrich our Cloud Native life.
