OS Migration Solution on Cloud | 云上操作系统迁移解决方案 – Jianlin Lv, eBay
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。
