Ubuntu Core 22 is Here for IoT and Edge Devices
|
||||
======
|
||||
Based on Ubuntu 22.04 LTS, Ubuntu Core 22 brings the best of security and performance for IoT and embedded devices.
|
||||
|
||||
![ubuntu][1]
|
||||
|
||||
Ubuntu Core 22 is a containerized Ubuntu 22.04 LTS variant optimized for embedded and IoT devices.
|
||||
|
||||
It should be a wonderful offering for developers looking to make use of Canonical’s latest operating system for edge devices.
|
||||
|
||||
To address the Ubuntu Core 22 release, **Mark Shuttleworth**, CEO of Canonical, said:
|
||||
|
||||
> “Our goal at Canonical is to provide secure, reliable open-source everywhere – from the development environment to the cloud, down to the edge and to devices,”.
|
||||
|
||||
### Ubuntu Core 22: What’s New?
|
||||
|
||||
![What is Ubuntu Core 22?][2]
|
||||
|
||||
With Ubuntu Core 22 release, you get improvements focused on security and reliability. Some of them include:
|
||||
|
||||
#### Real-time Compute
|
||||
|
||||
As the announcement mentions, Ubuntu 22.04 LTS provides a real-time kernel (which is available in beta), delivering high performance, ultra-low latency, and workload predictability fit for time-sensitive industrial, automotive, and robotics use cases.
|
||||
|
||||
Furthermore, if you have Ubuntu-certified hardware, you should be able to fully utilize advanced real-time features.
|
||||
|
||||
#### Snapcraft Framework
|
||||
|
||||
The entire Ubuntu image breaks down as packages (Snaps), making the kernel, OS, and the applications isolated in a sandbox.
|
||||
|
||||
This should let you easily install applications without needing to worry about dependencies from the dedicated IoT App Store. For enterprises, software management solutions through the App Store should enable a range of on-premise opportunities.
|
||||
|
||||
The framework also helps the system ensure the OTA updates work as expected, and do not break anything even if it fails for some reason.
|
||||
|
||||
#### Security
|
||||
|
||||
Out of the box, Ubuntu Core provides advanced security features that include secure boot, full-disk encryption, and more fit for mission-critical environments.
|
||||
|
||||
Note that you also get 10 years of security update commitment with this release.
|
||||
|
||||
#### Other Key Improvements
|
||||
|
||||
* Easy migration from Ubuntu Core 20 and ensuring backward compatibility.
|
||||
* Performance improvements.
|
||||
* A new factory reset boot mode, to factory reset from run/recovery modes.
|
||||
|
||||
For more information, you can refer to the [official a][3][n][4][nouncement][5].
|
||||

||||

Ubuntu Core 22 来了，适用于物联网和边缘设备
|
||||
======
|
||||
Ubuntu Core 22 基于 Ubuntu 22.04 LTS，为物联网和嵌入式设备带来了最佳的安全性和性能。
|
||||
|
||||
![Ubuntu][1]
|
||||
|
||||
Ubuntu Core 22 是一个容器化的 Ubuntu 22.04 LTS 变体，针对嵌入式和物联网设备进行了优化。
|
||||
|
||||
对于希望在边缘设备上运行 Canonical 的最新操作系统的开发者来说，这会是一个很棒的产品。
|
||||
|
||||
在发布 Ubuntu Core 22 时，Canonical 的 CEO **Mark Shuttleworth** 说：
|
||||
|
||||
> “Canonical 的目标是在任何地方提供安全、可靠的开源技术，从开发环境到云，再到边缘和设备。”
|
||||
|
||||
### Ubuntu Core 22 更新介绍
|
||||
|
||||
![什么是 Ubuntu Core 22？][2]
|
||||
|
||||
Ubuntu Core 22 版本带来了针对安全性和可靠性的改进。其中包括了以下几个改进。
|
||||
|
||||
#### 实时计算
|
||||
|
||||
正如公告中提到的，Ubuntu 22.04 LTS 提供了一个实时内核（测试版可用），它能为那些时间敏感的工业、汽车和机器人用例，提供高性能、超低延迟和工作负载可预测性。
|
||||
|
||||
此外，如果你有 Ubuntu 认证的硬件，你还能充分利用高级的实时功能。
|
||||
|
||||
#### Snapcraft 框架
|
||||
|
||||
整个 Ubuntu 映像分解为许多个包（快照），使得内核、操作系统和应用程序隔离在一个沙箱中。
|
||||
|
||||
这可以让你轻松地安装应用程序，而无需担心来自专用 <ruby>物联网应用商店<rt>IoT App Store</rt></ruby> 的依赖。对于企业而言，通过软件商店进行的软件管理解决方案，应该能够带来一系列内部部署的机会。
|
||||
|
||||
该框架还可帮助系统确保 OTA 更新按预期工作，即使由于某种原因失败，也不会破坏任何内容。
|
||||
|
||||
#### 安全
|
||||
|
||||
Ubuntu Core 提供了高级安全功能，包括安全启动、全盘加密以及一些更适合任务关键型环境的功能。
|
||||
|
||||
注意，此版本还提供了 10 年的安全更新承诺。
|
||||
|
||||
#### 其他关键改进
|
||||
|
||||
* 支持从 Ubuntu Core 20 轻松迁移并确保向后兼容性。
|
||||
* 性能改进。
|
||||
* 新的“恢复出厂设置”启动模式，以便在“运行/恢复模式”中恢复出厂设置。
|
||||
|
||||
