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](https://itsfoss.com/centos-stream-faq/)，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](https://www.redhat.com/en/about/press-releases/red-hat-defines-new-epicenter-innovation-red-hat-enterprise-linux-9)，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](https://www.redhat.com/en/blog/whats-new-rhel-90-beta) 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](https://www.redhat.com/en/store/linux-platforms) 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](https://developers.redhat.com/products/rhel/overview) 免费在一些系统上测试它。

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](https://itsfoss.com/centos-stream-faq/?ref=news.itsfoss.com), 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](https://www.redhat.com/en/about/press-releases/red-hat-defines-new-epicenter-innovation-red-hat-enterprise-linux-9?ref=news.itsfoss.com), 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](https://news.itsfoss.com/kernel-5-14-release/)

You can refer to [RHEL 9 beta release notes](https://www.redhat.com/en/blog/whats-new-rhel-90-beta?ref=news.itsfoss.com) 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](https://www.redhat.com/en/store/linux-platforms?ref=news.itsfoss.com) 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](https://linuxhandbook.com/get-red-hat-linux-free/?ref=news.itsfoss.com).
