With WASI Preview 2 and the Component Model finalized, Spin, Wasmtime, Wasmer, WasmEdge, wasmCloud, Lunatic, and Extism have expanded WASM into servers, edges, and embedded devices. We unpack Cloudflare Workers, Fastly Compute@Edge, AWS Lambda + WASM, Docker WASM, JS Components via JCO, WIT interface types, polyglot Rust/Go/Python/Java/AssemblyScript examples, capability-based security, and AOT compilation performance — across 26 chapters.

WASI Preview 2와 Component Model이 정식화되면서 Spin, Wasmtime, Wasmer, WasmEdge, wasmCloud, Lunatic, Extism이 서버, 엣지, 임베디드까지 영역을 넓혔다. Cloudflare Workers, Fastly Compute@Edge, AWS Lambda WASM 런타임, Docker WASM, JCO를 통한 JS Component, WIT 인터페이스 타입, 폴리글랏 Rust·Go·Python·Java·AssemblyScript 예제, 캐퍼빌리티 보안 모델, AOT 컴파일 성능까지 — 26개 챕터로 정리한다.
