看serverless有点迷糊， 这篇文整理了一些我的疑惑以及在对应的解答。
-
应用场景有哪些（associated with “on-demand” functionality）
-
data processing (e.g., batch processing, stream processing, extract-transform-load (ETL))
-
Internet of things (IoT) services for Internet-connected devices,
-
creating APIs for already built applications without breaking down or modifying the current or existing functionality of the application.

Comparsion with PaaS application hosting services✅
-
Platform as a service (PaaS) application hosting services is similar to FaaS in that they also hide “servers” from developers. However, such hosting services typically always have at least one server process running that receives external requests. Scaling is achieved by booting up more server processes, which the developer is typically charged directly for. Consequently, scalability remains visible to the developer.[5]
-
By contrast, FaaS does not require any server process constantly being run. While an initial request may take longer to be handled than an application hosting platform (up to several seconds[6]), caching may enable subsequent requests to be handled within milliseconds. As developers only pay for function execution time (and no process idle time), lower costs at higher scalability can be achieved (at the cost of latency).

serverless framework 跟云厂商提供的云函数服务和宣称的serverless有什么关系？ ✅
- serverless是一种理念，而serverless framework可以看做是一个脚手架工具，有了他，可以方便地在本地开发，然后一键部署到云平台上。二者不属于同一个组织。
