This document discusses developing serverless applications with Azure Functions. Azure Functions allow processing of events using small, isolated pieces of code called functions. Functions can be triggered by events from other Azure services and external sources. Functions are easy to develop, scale automatically, and only charge for the time spent processing events.

9. Azure Functions (函式)
以無伺服器之程式處理事件
使組合雲端應用變得容易
可使用 C#, Node.js, F#, Python, PHP, Batch 與更多種語言開發函式
容易跨服務排程事件驅動任務
以 HTTP API 終端點暴露函式
基於客戶需求擴展函式
容易與 Logic App 整合
