A Practical Guide to WebAssembly in Cloud Native
1. Introduction to WebAssembly WebAssembly (Wasm) is a general-purpose bytecode technology that compiles program code from other programming languages (e.g. Go, Rust, C/C++, etc.) into bytecode programs that can be executed directly in the browser environment.
One of the original goals of WebAssembly was to solve the performance problems of JavaScript by allowing Web applications to achieve performance similar to native applications. As a generic, open, and efficient abstraction of the underlying VM, many programming languages, such as C, C++, and Rust, allow existing applications to be compiled into Wasm’s object code so that they run in the browser.
