红帽宣布 RHEL 9：企业 IT 的下一代骨干系统
|
||||
======
|
||||
|
||||
> RHEL 9 是使用 CentOS Stream 构建的最新升级版。这也是其在 IBM 旗下发布的第一个主要版本。
|
||||
|
||||
![红帽 9][1]
|
||||
|
||||
红帽企业 Linux（RHEL）无疑是开源企业生态系统中的一个重要角色。
|
||||
|
||||
可能你记得，IBM 在 2019 年以 340 亿美元收购了红帽公司。因此，可以说，RHEL 8 是它被收购前的最后一个主要版本。
|
||||
|
||||
多年来，RHEL 8 已经有了几次更新。
|
||||
|
||||
最后，红帽宣布发布了 RHEL 9，作为为企业 IT 基础设施提供动力的下一代升级版本。
|
||||
|
||||
在这里，让我重点介绍一下该版本的主要新增功能。
|
||||
|
||||
### RHEL 9 的新变化
|
||||
|
||||
请注意，该平台将在未来几周内普遍提供。但是，既然已经正式宣布，应该不会花很长时间。
|
||||
|
||||
如果你是一个 Linux 桌面用户，也不关心云创新，你会发现有许多技术术语。你需要参考红帽的官方文档来了解它们。
|
||||
|
||||
如果你已经在使用 [CentOS Stream][2]，你可能对 RHEL 9 的升级有一定的了解。
|
||||
|
||||
是的，RHEL 9 是第一个由 CentOS Stream 构建的生产版本。
|
||||
|
||||
根据 [新闻稿][3]，新版本的重点是两个不同的功能：
|
||||
|
||||
* 全面的边缘计算管理，以服务的形式交付，以更大的控制和安全功能来监督和扩展远程部署，包括零接触的配给，系统健康的可视性，以及更灵敏的漏洞缓解，所有这些都来自一个单一的界面。
|
||||
* 通过 Podman（RHEL 的集成容器管理技术）自动回滚容器，它可以自动检测新更新后的容器是否无法启动，然后将容器回滚到以前的工作版本。
|
||||
|
||||
其他主要亮点包括：
|
||||
|
||||
* 一个新的镜像构建器服务。
|
||||
* 与 AWS Graviton 处理器的整合。
|
||||
* 针对 Spectre 和 Meltdown 等硬件级安全漏洞的改进。
|
||||
* 引入一个新的完整性测量架构。
|
||||
* WireGuard VPN 技术（无支持的技术预览）。
|
||||
* 改进了自动化。
|
||||
* Python 3.9
|
||||
* Node.js 16
|
||||
* Linux 内核 5.14
|
||||
|
||||
你可以参考 [RHEL 9 测试版发布说明][4] 以了解更多关于该版本的信息。
|
||||
|
||||
### 总结
|
||||
|
||||
虽然该版本可能不具有最新和最伟大的技术，但这些更新特性和功能应该有助于为较新的 IT 需求提供增强的支持。
|
||||
|
||||
最新版本应该在未来几周内通过红帽客户门户和云供应商市场提供。如果你不了解，可以在 [官方网站][5] 上查看这个 Linux 平台的定价。
|
||||
|
||||
当然，你也可以通过 [红帽开发者计划][6] 免费在一些系统上测试它。

Red Hat Enterprise Linux 9 Announced as the Next-Gen Backbone of Enterprise IT
|
||||
======
|
||||
RHEL 9 is the latest upgrade built using the CentOS Stream. It’s the first major release under IBM as well.
|
||||
|
||||
![red hat 9][1]
|
||||
|
||||
Red Hat Enterprise Linux is undoubtedly a significant player in the open-source enterprise ecosystem.
|
||||
|
||||
If you didn’t know, IBM acquired it for $34 Billion in 2019. So, it is safe to say that Red Hat Enterprise Linux 8 was the last major release before the acquisition.
|
||||
|
||||
There have been several updates to RHEL 8 over the years.
|
||||
|
||||
Finally, Red Hat announced the release of Red Hat Enterprise Linux 9 as the next-gen upgrade to power up enterprise IT infrastructure.
|
||||
|
||||
Here, let me highlight the key additions to the release.
|
||||
|
||||
### Red Hat Enterprise Linux 9: What’s New?
|
||||
|
||||
Note that the platform will be generally available in the coming weeks. But, now that it is officially announced, it should not take long.
|
||||
|
||||
If you are a Linux desktop user and aren’t concerned about cloud innovation, you will find numerous technical jargon. You will need to refer to Red Hat’s official documentation to know more about them.
|
||||
|
||||
If you’re already using [CentOS Stream][2], you might have an idea about the RHEL 9 upgrade.
|
||||
|
||||
Yes, RHEL 9 is the first production release built from CentOS Stream.
|
||||
|
||||
As per the [press release][3], the new version focuses on two different capabilities:
|
||||
|
||||
* Comprehensive edge management, delivered as a service, to oversee and scale remote deployments with greater control and security functionality, encompassing zero-touch provisioning, system health visibility, and more responsive vulnerability mitigations all from a single interface.
|
||||
* Automatic container roll-back with Podman, Red Hat Enterprise Linux’s integrated container management technology, which can automatically detect if a newly-updated container fails to start and then roll the container back to the previous working version.
|
||||
|
||||
Other key highlights include:
|
||||
|
||||
* A new image builder service.
|
||||
* Integration with AWS Graviton processors.
|
||||
* Improvements to address hardware-level security vulnerabilities like Spectre and Meltdown.
|
||||
* Introducing a new integrity measurement architecture.
|
||||
* WireGuard VPN technology is available as an unsupported technology preview.
|
||||
* Improved automation.
|
||||
* Python 3.9
|
||||
* Node.js 16
|
||||
* Linux Kernel 5.14
|
||||
|
||||
You can refer to [RHEL 9 beta release notes][4] to know more about the release.
|
||||
|
||||
### Wrapping Up
|
||||
|
||||
While the release may not feature the latest and greatest technologies, updated features and capabilities should help provide enhanced support for newer IT requirements.
|
||||
|
||||
The latest version should be available in the coming weeks via the Red Hat Customer portal and cloud provider marketplaces. You can check the pricing for Linux platforms on the [official site][5] if you’re new.
|
||||
|
||||
Of course, you can also get free access to it for some systems to test through the [Red Hat Developer programs][6].
