基于 Kubernetes 构建标准可扩展的云原生应用管理平台-孙健波、周正喜is organized around the concept of an application. Kubernetes is not a platform as a service (PaaS) and doesn‘t have or enforce a formal notion of an application. Instead, applications are informal and and described with metadata. The definition of what an application contains is loose.” Sited: https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/ API 和业务原语 关注点不同 服务语义与抽象程度不同 PaaS 层 UI (e.g. dashboard, cli) 用户 CUE schema/模板 “客户端”抽象 标准化的“服务端”抽象 – 应用模型 Open Application Model (OAM) • 通过 OAM spec 定义“以应用为中心”的原语 • 打破“谷仓”!

23-云原生观察性、自动化交付和 IaC 等之道-高磊付环境中是不同的,而传统交付方式 缺乏脚本能“理解”的方式来表达这些 差异,此外由于事后更新OS、三方库 或者系统,这些变更又缺乏校验关系, 升级时很难给予企业信心,这种交付 方式很难被自动化。 标准化能力-微服务PAAS-OAM-万花筒PAAS-1-引子 客户环境交付 制品 • 云应用交付最难的还不是RT的 碎片化,最难的是环境依赖的 碎片化,比如,硬件环境、网 络环境、运维规范等的碎片化。 尤其是运维方面的差异化,必 人员而言是不友好的。应用 =Workload+运维特性+.......多种东西的集成,也无法在应用级别上进行管理。 ISV研发团队 标准化能力-微服务PAAS-OAM-万花筒PAAS-2 阿里和微软在19年发布了一个叫做OAM的规范,这是基于10年云原生道路锤炼得到的自动化交付方案 构建镜像 多区域分发 配置 ApplicationConfiguration Component ; • 平台无关与高可扩展:应用定义与平台层实现解耦,应用描述 支持任意扩展和跨环境实现; • 模块化应用运维特征:可以自由组合和支持模块化实现的运维 特征描述。 • Components:在 OAM 中,“应用”是由多个概念共同组合而成。第一个概念是: 应用组件(Components),它是整个应用的重要组成部分。应用组件既可以包括 应用运行所依赖的服务:比如 MySQL 数据库,也包括应用服务本身:比如拥0 码力 | 24 页 | 5.96 MB | 6 月前3
