# Alchemy and the next generation of infrastructure as code

Sam argues that infrastructure tools have accumulated layers around provider APIs. Alchemy reduces the resource model to stateful TypeScript functions with create, update, delete, tests, consistency checks, and idempotent recovery.
Idempotent recovery can repeat an operation without creating another change. [04:09](https://youtu.be/babOa4shATk?t=249) [06:01](https://youtu.be/babOa4shATk?t=361) [12:13](https://youtu.be/babOa4shATk?t=733)

He says constrained conventions make resource generation easier for coding agents. He also describes embedding the runtime in Durable Objects and workflows. [33:00](https://youtu.be/babOa4shATk?t=1980) [25:38](https://youtu.be/babOa4shATk?t=1538)
