1. SEC 13F
A filing with the Securities and Exchange Commission (SEC), also known as the Information Required of Institutional Investment Managers Form. It is a quarterly filing required of institutional investment managers with over $100 million in qualifying assets. Companies required to file SEC Form 13-F may include insurance companies, banks, pension funds, investment advisers and broker-dealers. This
form, which must be filed within 45 days of the end of each quarter, contains information about the investment manager and potentially a list of their recent investment holdings.
2. SEC 13D
A form that must be filed with the SEC under Rule 13D. The form is required when a person or group acquires more than 5% of any class of a company\'s shares. This information must be disclosed within 10 days of the transaction. Rule 13D requires the owner to also disclose any other person who has voting power or the power to sell the security.
3. SEC SC 13G, SC 13G/A
An SEC form similar to the Schedule 13D used to report a party&# 39;s ownership of stock that is over 5% of the company. Schedule 13G is shorter and requires less information from the filing party. Ownership of over 5% in a publicly-traded stock is considered to be significant ownership, and therefore must be reported to the public
Kubernetes 项目作为容器编排领域的事实标准， 成功推动了诸如阿里云 Kubernetes （ACK）等云原生服务的迅速增长。但同时我们也关注到，Kubernetes 的核心 API 资源比如 Service、Deployment 等，实际上只是应用中的不同组成部分，并不能代表一个应用的全部。也许我们可以通过像 Helm charts 这样的方式来尝试表达一个可部署的应用，可一旦部署起来，实际运行的应用中却依旧缺乏以应用为中心的约束模型。这些问题都反映出，Kubernetes 以及云原生技术栈需要一种以应用为中心的 API 资源来提供一个专注于应用管理的、标准的、高度一致的模型，这个 API 资源可以代表完整运行的应用本身，而不仅仅是应用模板或者一个应用的几个组成部分，这就是今天阿里云与微软联合宣布推出开放应用模型 Open Application Model （OAM）的原因。
