Build a Serverless WebAssembly App in Python using Spin
summary
Claims that WebAssembly will power the next wave of cloud compute, then shows concrete steps: create a serverless Python app with the Spin CLI in three commands and deploy with a fourth, build emits an app.wasm 2.5 MB file, Python runs because CPython is compiled to WASM via WASI, and a second demo calls Llama 2 for jokes. Benchmarks note cold start ~2 ms, discusses the component model and componentize-py for composing Rust/Python modules.
