01 Topic & Guest Introduction

"Kata Containers in Edge Computing"

Guest introduction
Li Feng has worked for Motorola, Samsung and other IT companies, and is now an independent developer. He has accumulated more than ten years of R&D experience on mobile platforms, and has mainly focused on the field of cloud computing/edge computing infrastructure in recent years. He is the main translator of the Chinese version of "Grey Hat Hackers 4th Edition: Ethics, Penetration Testing, Attack Methods and Vulnerability Analysis Techniques for Justice Hackers" and "Linux Defense in Malicious Network Environments". Have a strong interest and practical ability in technological innovation, enthusiastically participate in various activities in the open source community, participate in various IT conferences and share technology for many times.

Introduction
The light weight and high security features of Kata Containers make it have a good application prospect in the IoT/edge computing field with limited resources and security requirements, and it can be further compared with other lightweight solutions (such as K3S, etc.) In conjunction with. This topic contains the following subtopics:
1) Kata Containers in LF Edge (formed by the merger of Akraino and EdgeX);
2) Create a lightweight K8S cluster-the combination of Kata-Containers and K3S;
3) Run Kata Containers in ACRN;
4) Apply Kata Containers to the edge cloud.

Audience gains
Understand the basics of Kata Containers
Understand the application prospects of Kata Containers in edge computing scenarios

"Fast Lightning: Nydus Image Acceleration Service"

Guest introduction
Peng Tao is a senior technical expert in the Trusted Native Technology Department of Ant Group, a Linux kernel and file system developer. In recent years, he has mainly focused on container runtime related technologies. He is the maintainer and member of the architecture committee of Kata Containers, and one of the authors of the Dragonfly mirroring service nydus , A staunch supporter of the wave of cloud native technology.
Xu Jihui, technical expert of the Trusted Native Technology Department of Ant Group, one of the authors of Dragonfly mirroring service nydus, responsible for the landing of nydus in Ant

Introduction
Studies have shown that container image pull occupies 70% of the container startup time, and container startup actually only needs to access less than 6% of the data volume of the container image. Based on this, we designed and implemented the nydus image acceleration service that can load container images on demand, deployed on a large scale internally, and contributed to the Dragonfly community as an open source. This topic will introduce you to the background, architecture and technical details of the nydus project, as well as our outlook on the container mirroring ecosystem.

Audience gains
Understand the advantages and disadvantages of the current OCI container image format
Understand the background, architecture and technical details of the nydus project
Understand the development trend of container mirroring ecology

"WebAssembly Micro Runtime: A new ultra-lightweight sandbox in the cloud-native era"

Guest introduction
Wang Xin, Intel senior engineering manager, creator of WAMR (WebAssembly Micro Runtime) project, mainly focuses on the management of language runtime and Web technology. Since 2009, he has led the development of Java and WebAssembly virtual machine runtime and the performance of V8 JavaScript engine. Optimization and other related work. Before joining Intel, he was mainly a technology leader at Motorola, responsible for work related to wireless base station systems.

Introduction
In recent years, WebAssembly has become more and more popular in server-side and cloud-native scenarios. WAMR (WebAssembly Micro Runtime) is a WebAssembly independent runtime open source project under the Bytecode Alliance. It supports a variety of software and hardware platforms, and supports interpreters/ Multiple execution methods such as AOT/JIT have excellent performance, low resource occupation, and good support for multi-threading and SIMD. This sharing will introduce WAMR's architecture, features, community cooperation and its application in cloud-native scenarios.

Audience gains
Learn about the emerging technology of WebAssembly
Understand the architecture, features and community cooperation of the WAMR open source project
Understand the application examples of WAMR in cloud-native scenarios

"Exploration and Practice of WebAssembly in MOSN"

Guest introduction
Ye Yongjie is a software engineer in the Trusted Native Technology Department of Ant Group and a core member of the open source project MOSN. He currently focuses on cloud native ServiceMesh, WebAssembly and other related fields.

Introduction
​With the large-scale implementation of the cloud-native data plane MOSN within Ant Financial, security isolation has gradually become one of the urgent problems to be solved. To this end, we use WebAssembly's security model based on given resources and rely on the community Proxy-Wasm open source specification to provide an independent and isolated sandbox environment for extensions in MOSN. This sharing will introduce the background of MOSN, the practice of WebAssembly in MOSN, and our contribution to the Proxy-Wasm open source specification.

Audience gains
Understand the basics of the cloud-native data plane MOSN
Understand the basic situation of Proxy-Wasm open source specification
Understand the practical cases of WebAssembly technology in the cloud-native data plane
