embly VS lunatic

Hey, I tried to build something like this too: https://github.com/embly/embly

My takeaway after building that is that the build tooling is the major pain point. If you're trying to onboard someone onto this platform from their favorite language the hard part is getting from code to the .wasm file. wasm-bindgen (as an example) has put so much effort into build tooling, I wonder if that's a necessary path for success here.

It's also great that WASI exists now, if I had to do embly again I'd just use wasi and then implement all of my "platform" features as filesystem features, not syscalls. If your API interface is the filesystem then you could provide interoperability between environments. Let's say you want to include a key-value store in the wasi runtime, you just make the keys files and the values file contents. Then you could so something like ship a FUSE filesystem to interact with the filesystem in the same way from a traditional VM or on a personal computer. I got really bogged down in custom syscalls and this path seems potentially more elegant.

Have you also thought about live process migration? I got really excited about this from a technical standpoint. Since you completely control the runtime you could set up a clustered wasm solution that moves long running processes from VM to VM by sending their live memory state to another machine. Not sure if that's actually useful, but cool that it's not bogged down by the usual complexities of doing the same in a full OS environment.

Anyway, so glad to see that someone is taking this idea on. Please make a cloud platform and let me pay for it. Also happy to chat more if any of this is useful, I've joined your discord as "max".

This reminds me of Lunatic [1], an Erlang-inspired runtime for WebAssembly. Unfortunately it seems like development stalled some months ago.

you can check out https://github.com/lunatic-solutions/lunatic for that

Very cool, and the approach demonstrated might be of interest to a similar problem we have in Ambient (our WASM game runtime that has competing processes that may need to retry interactions.)

That being said - what’s the relation to Lunatic [0]? Are you still working on Lunatic? Is this a side project? Or is it something completely separate?

Curious too. I follow Lunatic [0] as a candidate for future use, and also wasmCloud [1].

Check out Lunatic https://lunatic.solutions/

There's a couple of Rust libs and frameworks inspired on Erlang in 'best of both worlds' attempts, such as https://lunatic.solutions

I found others like Lunatic before, but cannot remember right now.

There is a really good initiative called Lunatic : https://lunatic.solutions/
