Executing workloads in the Hyperlight Wasm guest isn’t just possible for compiled languages like C, Go, and Rust, but also for interpreted languages like Python, JavaScript, and C#. The trick here, much like with containers, is to also include a language runtime as part of the image. For example, for JavaScript, the StarlingMonkey JS Runtime was designed to natively run in WebAssembly.

This is a significant breakthrough in software architecture. 

Not only is this architecture good for start times, fast start times also affect the way you can schedule your applications. If starting a workload takes about a millisecond, you can afford not to have any idling instances. If you do choose to have a warm pool ready, the memory footprint is drastically smaller. It also allows you to do more work on cheaper hardware, located closer to users. That’s the logic behind our upcoming Azure Front DoorEdge Actions service, powered by Hyperlight and soon to be in private preview.
