Microsoft Announces 'Hyperlight Wasm': Speedy VM-Based Security at Scale with a WebAssembly Runtime

Cloud providers like the security of running things in virtual machines "at scale" — even though VMs "are not known for having fast cold starts or a small footprint..." noted Microsoft's Open Source blog last November. So Microsoft's Azure Core Upstream team built an open source Rust library called Hyperlight "to execute functions as fast as possible while isolating those functions within a VM."
