This article explains what WebAssembly is, why its relevant to the Docker ecosystem, and provides hands-on examples. WebAssembly is an open standard that enables the creation of portable binary executables from different source languages, allowing traditional desktop apps to run on any device with a browser. Wasm runtimes can run outside of the browser and communicate with the outside world using different interfaces, making it attractive for server-side development. Wasm is open, fast, and secure, ensuring that a Wasm application can access only what its explicitly allowed to.
