Cloud Native WASM: What's All the Hype?
summary
Claim: Cloud-native WASM produces tiny, fast server binaries—demo compiles Rust with the wasm32 target, packages via Docker buildx (--platform=wasm/wasm) and runs using the runwasi shim + WasmEdge runtime under containerd. Measured image is ~500 KB versus a comparable 4.9 MB container; cold starts are much faster, so current sweet spots are event-driven FaaS and edge. Docker Desktop 4.15 exposes the wasm beta and the demo build and run succeed.
