Nanos Reviews and Details

Is Nanos good?

• Show HN: Ant – A JavaScript Runtime and Ecosystem

  On linux its kvm, on darwin its hypervisor.framework, the memory is not upfront, by default 256mb is lazy allocated, and ~35mb are used by both ant + the vm. The kernel is https://nanos.org with patches to get ant+networking running smoothly. - Source: Hacker News / 9 days ago

• NanoVMs

  (I'm w/NanoVMs). Firecracker is a complementary technology and not competitive. Our main software - https://nanos.org is a linux kernel guest replacement whereas firecracker is a VMM (host) replacement for something like qemu. So the vast majority of our users deploy to AWS, GCP, etc. And those deploys are created as ec2 instances (but without linux). Some of our users/customers use firecracker for ephemeral... - Source: Hacker News / about 1 year ago

• BareMetal OS

  Then maybe a unikernel such as Nanos would work better for you. https://nanos.org/. - Source: Hacker News / over 1 year ago

• Asterinas: OS kernel written in Rust and providing Linux-compatible ABI

  This is a very large rationale for what we are building with https://nanos.org . - Source: Hacker News / almost 2 years ago

• OS for Secure Containers?

  Going to toot my own horn here but if you're looking for something like a container with a security focus that is precisely what https://nanos.org was built for. No users, no login/ssh, no ability to run other programs other than the one that is already running. It kills off entire CWE's such as CWE-77/CWE-78 and neutralizes a large amount of nasty payloads forcing attackers to put in the work. It has all the same... - Source: Hacker News / almost 2 years ago

• Show HN: Convert your Containerfile to a bootable OS

  Erlang on Xen was most definitely an inspiration behind what we're working on with https://nanos.org . - Source: Hacker News / about 2 years ago

• Nanos – A Unikernel

  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. - Source: Hacker News / over 2 years ago

• Nanos – A Unikernel

  Forgot to mention this but https://nanos.org is also related with https://nanovms.com (to deploy unikernels) and ops.city (which handles the package distributions), so it's like a whole ecosystem. I wonder why Alpine linux won over this though? - Source: Hacker News / over 2 years ago

• Kolibri OS: fits on a floppy disk, programmed using interrupts

  I work with https://nanos.org && https://ops.city - we can run thousands of these on commodity hardware. - Source: Hacker News / over 2 years ago

• Mirage – A programming framework for building type-safe, modular systems

  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). - Source: Hacker News / over 2 years ago

• Build Your Own Docker with Linux Namespaces, Cgroups, and Chroot

  Https://nanos.org/ Seems to be a living concept still, just not in the mainstream. - Source: Hacker News / about 3 years ago

• Running Postgres as a Unikernel

  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... - Source: Hacker News / about 3 years ago

• Applications available in unikernels?

  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... Source: about 4 years ago

• Ask HN: Software with biggest potential for positive impact in 5 years?

  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... - Source: Hacker News / over 4 years ago

• Unikernels: The Next Stage of Linux's Dominance

  For instance the filesystems have no permissions because there are no users because it is only running one process. Linux is ~30M LOC and half of that is drivers. When you deploy to a cloud you only really need a handful of drivers - something to talk to the disk, the network, a clock, etc. That's very different than deploying to bare metal servers where you have hundreds of different nics, usb, disk drives, etc....

• OSv Unikernel – Optimizing Guest OS to Run Stateless and Serverless Apps

  This isn't true. Both https://nanos.org and https://ops.city are Go unikernels running on Google Cloud. (I'm with NanoVMs that is the maintainer of these projects.). - Source: Hacker News / almost 5 years ago
