Docker Desktop has run on microVMs since its 2016 launch

A Docker engineer recounts that Docker Desktop (originally Docker for Mac) was built on a custom-built lightweight VMM called hyperkit, developed from Docker's Mirage Unikernel libraries, running a minimal LinuxKit-based kernel. This architecture replaced VirtualBox, which had powered the earlier Docker Toolbox, and has since evolved into what the company now calls Docker VMM.

Netlify moves Edge Functions to Firecracker MicroVMs, cuts median latency 5x

Netlify has re-architected the infrastructure behind its Edge Functions, replacing a hosted execution service with Firecracker MicroVMs running directly on its own edge network. The company, working with Unikraft, says warm invocations now take roughly 5-6ms at the median, down from 25-40ms previously, while functions can still be written and deployed exactly as before.
