ops-examples VS unikraft

Yeh - we have a small language list here:

https://github.com/nanovms/ops-examples

If you're looking for a particular piece of software search on the repo first:

https://repo.ops.city/

If you don't find it and need help creating one ping me or open an issue in ops.

Nanos runs not just go but pretty much any language you want to throw at it:

https://github.com/nanovms/ops-examples .

FYI, erlang && elixir workloads can run on Nanos: https://github.com/nanovms/ops-examples/tree/master/elixir .

I do understand what you are asking for though. There used to be an older project called erlang-on-xen: https://github.com/cloudozer/ling .

It'd be great to see this idea revisited although you'll need to create some sort of new handling/framework.

See for example nanovm provides examples for a bunch of different languages, including this in Chicken Scheme https://github.com/nanovms/ops-examples/tree/master/scheme/01-hello-world ...I expect Racket would be possible too

You should also probably check out Unikraft (https://unikraft.org) , supports many languages/apps, x86/ARM64 and QEMU/Firecracker. Is also able to run an ELF built under Linux as a unikernel (see https://unikraft.org/guides/bincompat). Discord is at https://unikraft.org/discord .

>"For performance-oriented UDP-based apps, much of the OS networking stack is useless:

the app could simply use the driver API, much like DPDK-style applications already do.

There is currently no way to easily remove just the network stack but not the entire network sub-system from standard OSes."

This page is a great read for any current or future OS developer...

unikernel is not the same microkernel.

Wow, just now seeing this topic. I work for a cloud company hosted in AWS. We started out, Netflix/Spotify style microservices. We were all on ec2 images generate by packer (and later with AWS Image Factory). When Docker hit, we kicked the tires but never did anything with it beyond using it for running unit tests, and later, infrastructure tests. 5 years ago, during a hackathon, our little group began experimenting with Unikernels, or library operating systems. Interestingly enough, these Unikernels were all stripped down BSD kernels. OSv is FreeBSD based, and Rumprun is NetBSD based. Services running in EC2 on Unikernels would spin up and start sending and receiving traffic before the AWS EC2 healthchecks completed. They are blazing fast! Only problem in 2017, was the tooling. It would have taken too much effort to use Unikernals with our infrastructure. As soon as they start making Unikernels that can run Java bytecode like native code, the fate of containerization will be sealed, IMO. We could get basic JVM webservers running on OSv, but not Cassandra, not Kafka, not yet. OSv now runs on Firecracker, but I have not tried it out, yet. Some links if you are interested: OSv: https://osv.io Rumprun: https://github.com/rumpkernel/rumprun We used this tooling during the Hackathon, but doesn't look like it has been touched in 3 years: https://github.com/solo-io/unik Unikraft Unikernel Dev kit: https://unikraft.org/ And don't forget Firecracker running in Kubernetes https://www.weave.works/oss/firekube/ And of course, being a FreeBSD subreddit, let's not forget FreeBSD on Firecracker https://www.daemonology.net/blog/2022-10-18-FreeBSD-Firecracker.html
