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”!
