Service mesh technology has revolutionized service governance among microservices, but as clusters expand, challenges arise. Proxy programs can strain resources, with memory consumption reaching GB levels and CPU overhead peaking at 30%. Furthermore, this expansion often leads to noticeable delays in microservice access. This call for proposals seeks to address these challenges head-on by exploring innovative solutions within the kernel-native sidecarless service mesh framework. We invite submissions that delve into: Efficient Resource Management: Novel strategies to minimize memory consumption and CPU overhead in proxy programs, ensuring optimal resource utilization. Latency Optimization: Techniques to reduce microservice access latency without compromising on service governance effectiveness. Real-world Implementations: Case studies or examples showcasing successful deployments of kernel-native sidecarless service mesh in diverse environments.

服务网格技术已经在微服务之间的服务治理方面发生了革命，但随着集群的扩大，也带来了挑战。代理程序可能会消耗资源，内存消耗可能达到GB级别，CPU开销可能达到30%。此外，这种扩展通常会导致微服务访问出现明显的延迟。 本次征集旨在通过探索内核本地无边车服务网格框架中的创新解决方案来直面这些挑战。 我们邀请提交以下内容的提案： 高效资源管理：采用新颖策略来最小化代理程序的内存消耗和CPU开销，确保资源的最佳利用。 延迟优化：通过技术手段减少微服务访问延迟，同时不影响服务治理的有效性。 实际应用：展示在不同环境中成功部署内核本地无边车服务网格的案例研究或示例。

Each Linux distribution has a lifecycle; this refers to when the OS developers stop providing updates or any form of support. Continuing to use EOL Linux poses risks such as security vulnerabilities, compatibility issues, and lack of official support. Cloud providers face the challenge of quickly and safely migrating OS to a supported distribution. There are several challenges involved in the process of migrating OS: 1. Ensuring the safety of application data, which is especially significant during OS migrations between different Linux distributions; 2. Customizing the OS based on the Linux distribution, which includes changes to the kernel, deb packages, specific configurations, and tools; 3. How to quickly rollout new OS to the production environment. Achieving the goal of transitioning over 100,000 physical nodes each month without affecting customer operations and minimizing node downtime. This talk will detail the issues encountered in OS migration and the proposed solutions.

每个Linux发行版都有一个生命周期；这指的是当操作系统开发者停止提供更新或任何形式的支持时。继续使用EOL Linux会带来风险，如安全漏洞、兼容性问题和缺乏官方支持。 云服务提供商面临着快速且安全地将操作系统迁移到受支持的发行版的挑战。 在迁移操作系统的过程中涉及到几个挑战： 1. 确保应用数据的安全性，在不同Linux发行版之间迁移操作系统时尤为重要； 2. 根据Linux发行版定制操作系统，包括对内核、deb软件包、特定配置和工具的更改； 3. 如何快速将新操作系统推出到生产环境。实现每月迁移超过10万个物理节点的目标，同时不影响客户运营并最小化节点停机时间。 本次演讲将详细介绍操作系统迁移中遇到的问题和提出的解决方案。
