Server-side Wasm Applications: Replacing Docker with WASI

on YouTube ↗56m

" summary

Argues that server‑side WebAssembly (WASI) can replace Docker for many stateless microservices by rebuilding a Java image as a Rust WASM module and running it with wasmtime/Spin/wasmCloud. Concrete results: a Java Docker image shows 672 vulnerabilities and needs 100 seconds startup with a 3 GB heap and 296 MB artifact, while the Rust WASM rebuild produces a 3 MB artifact and runs background‑removal demos in 25 ms end‑to‑end. Works for image processing and ~100 MB ML inference (~1s); current limits include no outbound networking, no threads and GC challenges.
