WebAssembly: The Next Frontier of Cloud Computing
summary
WebAssembly is presented as offering near-native performance and CPU portability for cloud workloads by compiling Rust to .wasm and running it on Node and in browsers. Demos show a WASI file-copy failing until directory permissions are granted to illustrate WASI capability-based sandboxing, and tooling/runtimes covered include wasmPack, wasiTime, WasmEdge, Spin, RunWASI, Cloudflare Workers, an OCI Docker+Wasm image build (Beta), and Fermion/Spin claiming faster startup than AWS Lambda.
