事件是事件驱动架构或无服务器应用中常见的机制。然而，生产者或云提供商通常以不同形式支持它们，这阻碍跨平台和基础架构的互操作性。CloudEvents 是一个描述事件数据的通用格式的规范，旨在提供服务、平台和系统之间的互操作性。它提供了多种编程语言的 SDK，因此您可以将规范嵌入到应用程序或工具链中。我们的团队不仅将其用于跨云平台的目的，还用于领域事件规范等其他场景。CloudEvents 由云原生计算基金会（CNCF）托管，现在作为孵化项目运行，已经获得了越来越多的行业关注。
Outside the function code itself, applications written as serverless functions are tightly coupled to the cloud platform on which they're hosted. Although events are a common FaaS-triggering mechanism, and every cloud provider supports them in some form, the current proprietary specifications prevent interoperability across clouds. The CloudEvents specification is a burgeoning standard that has been accepted into the CNCF Sandbox. The standard is still in active development but several language bindings exist and Microsoft has announced first-class support in Azure. We're hoping other cloud providers will follow suit.
