应用程序可能具有更高的实时要求,这使得硬件平台、位置和/或安全意识成为一项要求。开发人员需要了解更多种类的硬件和接口。

| 这一广泛的使命对于边缘应用仍然适用,因为 [开放边缘计算术语表](https://github.com/State-of-the-Edge/glossary/blob/master/edge-glossary.md#edge-native-application) 指出,“边缘原生应用”参考了云原生原则: | ||
|
|
||
| >*“边缘原生应用程序是利用边缘计算能力构建的应用程序,不适合在中心云运行。边缘原生应用程序参考云原生原则,同时需要考虑边缘的独特特性,例如资源限制、安全性、延迟和自治性。边缘原生应用是利用云计算能力,并能与上游资源协同工作的方式构建的。不关心集中资源管理、远程管理、编排、 CI/CD 的边缘应用程序并不真正“原生”,而更类似于传统的本地应用程序。”* |

同上,中文需要堂堂正正,不要歪斜。
全文 应用程序 为 38 个,应用为 20 个,需要统一。个人倾向于应用
空格问题用 prettier 一条命令来解决就好

| | 稳定性 | 将稳定性外包给云提供商,使用分布在不同地域的冗余节点。 | 通常依赖于经过强化的基础设施,具有面向有状态组件的恢复架构;在许多情况下,稳定性可能比云上的稳定性低。 | | ||
| | 规模 | 通常限于少数区域和实例 | 可以支持大规模区域(高达数万个),支持大量外部设备(高达数十万个) | | ||
| | 编排 | 大型公有或私有云中的编排旨在通过在集中池化的主机上运行工作负载(以水平方式调度)来实现效率和可用性。 | 边缘是分散的,工作负载以分布式方式部署,通常以指定区域的方式调度。 | | ||
| | 管控 | 虽然云原生和边缘原生都是可管控的,但机制有所不同;云原生依赖于集中管控和自动化。 | 边缘原生需要远程和集中管控的混合方式以及硬件和软件的无接触部署。边缘的运维人员可能没有接受过培训,人数很少,甚至不存在。升级流程需要具有原子性和一致性,防止设备升级失败导致不可用。 | |

| 边缘计算使数据处理更接近源头,例如,在工厂中控制机器人。 未来五年,边缘计算将变得更加普遍,该行业预计从 [2022年到2030年将增长38.9%](https://www.grandviewresearch.com/industry-analysis/edge-computing-market). 很多公司正在看到以下将计算能力放在边缘的好处: | ||

| 有多种边缘计算定义存在,但本文将重点关注基于数据处理所处的地理位置的边缘计算。基于地理位置的边缘被分类为多个类别,具体取决于与用户的距离。下图显示了根据 [Linux 基金会边缘白皮书](https://www.lfedge.org/wp-content/uploads/2020/07/LFedge_Whitepaper.pdf) 定义的类别。 | ||

| “边缘原生”一词已在行业博文中的许多地方被提及,比如 [Gartner](https://blogs.gartner.com/thomas_bittman/2020/04/17/cloud-native-isnt-edge-native/)、 [Macrometa](https://www.macrometa.com/blog/edge-native-is-not-cloud-native)、 [FutureCIO](https://futurecio.tech/cloud-native-versus-edge-native-know-the-difference/)。而 [State of the Edge](https://github.com/State-of-the-Edge/glossary/blob/master/edge-glossary.md#edge-native-application) , [Linux Foundation](https://www.lfedge.org/wp-content/uploads/2020/07/LFedge_Whitepaper.pdf) (LF) 这些组织也在讨论边缘原生应用,但还没有关注边缘原生应用原则。 |
