Binary instruction format that allows code written in multiple languages to run at near-native speed in web browsers and on servers. Like having a universal translator that lets different programming languages run anywhere efficiently.
Game developers use WebAssembly to run complex 3D games in browsers with performance nearly matching native desktop applications.
WebAssembly (Wasm) is an open standard runtime format, not a single cloud service. All major clouds can run Wasm via containers/Kubernetes, serverless platforms, or edge runtimes using third-party or open-source Wasm runtimes (for example, Wasmtime, WasmEdge, or Spin). Some provider products may support Wasm in specific contexts, but there is no universal, provider-owned “WebAssembly service” equivalent across AWS, Azure, GCP, and OCI.
