关于AWS-Amazon Linux 2023-的发布与说明

发布时间 2023-06-10 15:23:41作者: 520_1351

因 目前Amazon Linux 1 已经在2020年12年31日 结束了标准支持,目前处于维护支持阶段,维护支持期将于 2023 年 12 月 31 日结束。

Amazon Linux 2 结束支持的日期为2025年6月30日,笔者在另一篇文章《关于Amazon Linux1 与 Amazon Linux2 - 操作系统-支持及生命周期的说明》中有写到详情

因此要升级即将停止支持的Amazon Linux 1 可以选择的有 Amazon Linux 2  与 Amazon Linux 2023

关于Amazon Linux 2023,笔者在如下官网站看到的是在 2023-03-15 宣告推出发布,并进行了说明:

Today, we are announcing the general availability of Amazon Linux 2023 (AL2023), our new Linux-based operating system for AWS that is designed to provide a secure, stable, high-performance environment to develop and run your cloud applications. AL2023 provides seamless integration with various AWS services and development tools and offers optimized performance for Amazon Elastic Compute Cloud (EC2) Graviton-based instances and AWS Support at no additional licensing cost. Starting with AL2023, a new Amazon Linux major release will be available every 2 years. This cadence provides you with a more predictable release cycle and up to 5 years of support, making it easier for you to plan your upgrades. 

AL2023 offers several improvements over Amazon Linux 2 (AL2). For example, AL2023 takes a security-by-default approach to help improve your security posture with preconfigured security policies, SELinux in permissive mode and IMDSv2 enabled by default, and the availability of kernel live patching. With deterministic upgrades through versioned repositories, you can lock to a specific version of the Amazon Linux package repository, giving you control over how and when you absorb updates. With this capability, you can adhere to operational best practices more efficiently by ensuring consistency between package versions and updates across your environment. For a full comparison, see Comparing Amazon Linux 2 and Amazon Linux 2023.

Amazon Linux 2023 is generally available in all AWS Regions, including the AWS GovCloud (US) and the China Regions. To learn more about Amazon Linux 2023, see the AWS documentation

 

今天,我们宣布正式推出 Amazon Linux 2023 (AL2023),这是我们基于 Linux 的 AWS 操作系统,专用于为开发和运行云应用程序提供安全、稳定、高性能的环境。AL2023 提供与各种 AWS 服务和开发工具的无缝集成,并针对基于 Graviton 的 Amazon Elastic Compute Cloud (EC2) 实例和 AWS Support 优化了性能,且无需支付额外的许可费用。从 AL2023 开始,Amazon Linux 全新主要版本将每 2 年发布一次。这种发布节奏使发布周期更加可预测,并提供了长达 5 年的支持,让您能够更轻松地规划升级。 

在 Amazon Linux 2 (AL2) 的基础上,AL2023 进行了多项改进。例如,AL2023 秉承预设安全原则,通过预先配置的安全策略、SELinux 宽容模式和默认启用 IMDSv2 以及内核实时修补的可用性来帮助改善您的安全状况。使用版本化存储库进行确定性升级时,您可以锁定到 Amazon Linux 软件包存储库的特定版本,从而控制吸收更新的方式和时间。借助此功能,您可以确保软件包版本和更新在环境中的一致性,从而更有效地遵循运营最佳实践。有关完整比较,请参阅比较 Amazon Linux 2 和 Amazon Linux 2023

Amazon Linux 2023 现已在所有 AWS 区域正式推出,包括 AWS GovCloud(美国)和中国区域。 如需了解更多有关 Amazon Linux 2023 的信息,请参阅 AWS 文档。
