# Happy Path 116: Infrastructure as effects

Sam argues that infrastructure tools can retain ordinary application-code properties such as debugging and tests. Effect gives Alchemy a pure program: it describes work before execution and can be planned first.
The program carries resource requirements in its context. [03:50](https://youtu.be/YEn4A7XxgF4?t=230) [12:22](https://youtu.be/YEn4A7XxgF4?t=742) [24:52](https://youtu.be/YEn4A7XxgF4?t=1492)

He shows how runtime operations relate to explicit infrastructure policies and deployed resources. The compiler can check those relationships before deployment. [28:00](https://youtu.be/YEn4A7XxgF4?t=1680) [30:31](https://youtu.be/YEn4A7XxgF4?t=1831) [34:03](https://youtu.be/YEn4A7XxgF4?t=2043)
