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 is an open standard, not a single managed cloud service. All major cloud providers can run or support WebAssembly indirectly through browsers, containers, serverless platforms, edge runtimes, Kubernetes, and developer tooling, but there is no direct one-to-one core service equivalent across AWS, Azure, Google Cloud, or OCI.
