AzureFunBytes is a weekly opportunity to learn more about the fundamentals and foundations that make up Azure. It’s a chance for me to understand more about what people across the Azure organization do and how they do it. Every week we get together at 11 AM Pacific on Microsoft LearnTV<\/a> and learn more about Azure.<\/p>\n

WebAssembly (or WASM) was introduced as a runtime for more highly performant in-browser applications. WASM workloads offer another exciting use case outside of the browser. WebAssembly’s sandbox, the ability to target multiple languages to a common runtime, and a very low overhead execution runtime provide an interesting option for true cloud native workloads. We’ll look at an experimental PaaS platform for running WebAssembly workloads – with a fully automated environment setup in Azure, use the yo wasm tool to get started quickly, and look at an existing preview feature in Azure Kubernetes Service where WASM workloads can be run today!<\/p>\n

From the Microsoft docs website<\/a>, WASM is described as: “…a binary format that is optimized for fast download and maximum execution speed in a WASM runtime. A WASM runtime is designed to run on a target architecture and execute WebAssemblies in a sandbox, isolated from the host computer, at near-native performance. By default, WebAssemblies can’t access resources on the host outside of the sandbox unless it is explicitly allowed, and they can’t communicate over sockets to access things environment variables or HTTP traffic.”<\/em><\/p>\n

The goals of WebAssembly include:<\/p>\n
