It's unlikely we'll open source the Elixir app, most of it isn't that interesting. But extracting the machine code into an example app is a good idea! Until then, here's a prototype go proxy that launches suspended machines when requests come in: https://github.com/superfly/machine-proxy

We'll be baking that into our proxy soon so we can handle lambda-type workloads.

Image size impacts the cold startup time since it gets fetched and converted into a rootfs before launching. Caching speeds up subsequent launches. Once a machines is created, it can be stopped and resumed, which is _much_ faster. I don't remember the numbers, but it's in the several hundred ms range.

We'll have more to share soon.
