Hyperlight: Virtual machine-based security for functions at scale


The Microsoft Azure Core Upstream team is excited to announce the Hyperlight project, an open-source Rust library you can use to create very small VMs for embedded functions. Learn more.

Prior to Hyperlight, to achieve low-latency cold starts, infrastructure providers needed to keep warm VMs at the ready to execute these bits of code. Hyperlight enables these customizations in a wide range of scenarios: for Internet of Things (IoT) gateway function embedding, usage in industrial automation, high-throughput cloud services, and so on. Hyperlight’s incubation and submission to a foundation builds on Microsoft efforts to empower developers by creating open, flexible technology for cloud and edge applications.
