Microsoft Azure has launched the Hyperlight project, a Rust language library for running small functions in a separate hypervisor to enhance security. Even if an application is hacked, hackers cannot penetrate other processes on the same machine.
The Hyperlight project takes approximately 1-2ms to start processing, which is between the normal sandbox runtime of less than 0.03ms and the old VM runtime of at least 120ms. Many have attempted to run applications directly on virtual machines, such as AWS’s Firecracker.
The Hyperlight project is open-source under the Apache 2.0 license, and Microsoft has also submitted the project to CNCF as a Sandbox project.
TLDR: Microsoft Azure introduces the Hyperlight project for secure running of small functions in a separate hypervisor, with improved processing times compared to traditional VMs.
