The article explores the role of WebAssembly (Wasm) in the technology landscape, particularly its application within Kubernetes. Rather than debating its comparisons to other technologies like JavaScript and Docker, the focus is on practical usage and implementation. The author highlights Rust as the primary source language to create WebAssembly, showcasing a specific use case of an HTTP server built with Rust that mimics a functionality from the httpbin API. The article differentiates between native Rust compilation and two WebAssembly runtimes, emphasizing the innovative opportunities WebAssembly presents for cloud computing.
WebAssembly is often debated as a JavaScript competitor or a new programming language, but its true potential lies in optimizing compute on Kubernetes.
Unlike traditional programming, WebAssembly is generated from other code. Languages like Go and Rust are currently paving the way for its use in cloud compute.
