nanos VS solo5

I am a bit confused, there are three sites:

* https://nanos.org/

* https://nanovms.com/

* https://ops.city/

And I am not sure what "thing" I am using. Is there some disambiguation? I know is OPS is the orchestration CLI, but I am confused at the difference between Nanos and NanoVMs. What should I call the section of my README that deals with this tech? Currently gone with Nanos/OPS but I am confused.

I work with https://nanos.org && https://ops.city - we can run thousands of these on commodity hardware.

Unik was just a build tool that utilized other projects like Rump, Mirage, IncludeOS, etc. It's now dead since Solo pivoted a very long time ago to service mesh/api gateways.

The GoRump port they use was from us and then we realized we needed to code our own from the ground up for many reasons so we wrote https://nanos.org (runs as a go unikernel in GCP).

A couple unikernel projects that caught my eye in the past may be of interest to you. I have no experience with them, so I can't speak to their quality though.

Definitely agree with the top part, however, I should note that, ops, the tool's, whole existence is to create disk images and upload them to any cloud, any hypervisor.

In particular, both https://ops.city && https://nanos.org are Go unikernels running on GCP and their deploys take just a few seconds to push out. AWS can be even faster cause we skip the s3 upload part. We also have lots of people using Azure which would be utilizing vhdx.

I'm with that organization that works on https://nanos.org and https://ops.city . If you aren't a software engineer but still would like to use unikernels you're in luck - we also have a package repository at https://repo.ops.city/ (running as a go unikernel on GCP) that will allow you to run and deploy pre-made applications. If you don't see something that you'd like to us there's also a way of importing docker containers into unikernels via ops which works for most (but not all) applications.

I think Unikernels like NanoVMs (https://nanos.org/) will become more important. They are more efficient and more secure than than full operating systems. Right now, I think there are no good monitoring solutions available (or at least I am not aware of any). You can't just ssh to your server, so if something goes wrong, it can be hard to debug. And they are certainly not integrated into bigger monitoring solutions like Dynatrace. But once the infrastructure is available, I would expect a large percentage of Linux servers to be replaced with unikernels.

What you already can do is attaching gdb -- either live or at a core dump. Please see https://github.com/Solo5/solo5/blob/master/docs/debugging.md for detailed instructions ;)

What you as well can do is record-replay -- well, at least there used to be this option, I'm now lost whether it has never been merged anywhere, or it is stuck in some PR somewhere. This was truly great - since the external interface is so thin, it is easily doable to dump all external events (API calls and returns) onto disk and replay one-by-one, inspecting the state.
