微服务 (Microservices) 是一种软件架构风格 (Software Architecture Style)，它是以专注於单一责任与功能的小型功能区块 (Small Building Blocks) 为基础，利用模块化的方式组合出复杂的大型应用程序，各功能区块使用与语言无关 (Language-Independent/Language agnostic) 的 API 集相互通信。微服务架构运用于软件架构风格的其中一项概念是甘露运算 (Dew Computing)，意指由许多的小露水 (代表微服务的功能组件) 汇集而成的运算能力。

In computing, microservices are small, independent processes that communicate with each other to form complex applications which utilize language-agnostic APIs. These services are small building blocks, highly decoupled and focused on doing a small task, facilitating a modular approach to system-building. The microservices architectural style is becoming the standard for building continuously deployed systems.
