近来serverless 的概念很火，StdLib这家把serverless 做得好简单啊，一条命令，CI都不用了。 https://github.com/stdlib/lib
引用官方的话：
StdLib is based on Function as a Service ("server-less") architecture, popularized by AWS Lambda. You can use StdLib to build modular, scalable web services for yourself and other developers in minutes without having to manage servers, gateways, domains, write documentation, or build SDKs. Your development workflow has never been easier - focus on writing code you love, let StdLib handle everything else.
可是这方面的原理是什么呢? 国内有类似的平台吗？
