What happened to the nice Ansible cloud (provisioning) listing?
That said... you might want to check out linuxkit
That said... you might want to check out linuxkit -- if you're ever in a place where you need to build VMs out of containers, it is looks next-generation (granted it is less powerful than ansible on a running machine).

Ask HN: How are you using unikernels?
The definition of what a unikernel is needs to be narrowed down, a lot of these projects in the space (not all the ones listed above) have material differences that are not clear:
- some run only one language
- some require recompilation
- some essentially swap out libraries, others do something closer to dropping your already mostly static binary in a minimal disk image
- some build pid1 processes, others VMs images
Anyway, here are some additional entries in the space:
- https://ssrg-vt.github.io/hermitux/
- https://github.com/linuxkit/linuxkit (more embedded/minimal VM than unikernel)
- https://nabla-containers.github.io/ (runs on Solo5)
I am going through using Linuxkit to build AMIs for cloud providers now. I wouldn’t necessarily class linuxkit as a universal project because it doesn’t have the hallmark blurring of user and kernel space or kernel-as-a-library but you can customize the kernel so it’s an adjacent idea, and I think it’s the one most likely to be in actual use at non-hyperscalers.

Unikraft: Fast, Specialized Unikernels the Easy Way
I believe there is growing interest in providing leaner, "trimmed" runtimes for services deployed to the cloud. Today, this is seen largely by specializing the Linux kernel for, for example, container services[0] or in general[1], as much as that is possible (the paper above covers this problem in greater detail). But, Unikernels in themselves are not yet widely adopted. This is the space Unikraft is aiming to enter, providing the ultimate level of specialization for a target application.
It's clear that bigger players, such as Red Hat[2] are interested in the topic of unikernels, and that cloud providers are preparing for this future too [3].

Docker Without Docker
I'm really impressed by fly.io, and the candidness with which they share some of their really awesome technology. Being container-first is the next step for PaaS IMO and they are ahead of the pack.
I aim to build a platform like theirs someday (probably not any time soon) but I don't think I'd do any of what they're doing -- it feels unnecessary. Bear with me as I recently learned that they use nomad[0] and some of these suggestions are kubernetes projects but I'd love to hear why the following technologies were decided against (if they were):
- kata-containers[1] (it does the whole container -> VM flow for you, automatically, nemu, firecracker) with multiple VMM options[2]
- linuxkit[3] (let's say you didn't go with kata-containers, this is another container->VM path)
- firecracker-containerd[4] (very minimal keep-your-container-but-run-it-as-a-VM)
- kubevirt[5] (if you just want to actually run VMs, regardless of how you built them)
- Ceph[6] for storage -- make LVM pools and just give them to Ceph, you'll get blocks, distributed filesystems (CephFS), and object gateways (S3/Swift) out of it (in the k8s space Rook manages this)
As an aside to all this, there's also LXD, which supports running "system" (user namespace isolated) containers, VMs (somewhat recent[7][8]), live migration via criu[9], management/migration of underlying filesystems, runs on LVM or zfs[10], it's basically all-in-one, but does fall behind in terms of ecosystem since everyone else is aboard the "cloud native"/"works-with-kubernetes" train.
I've basically how I plan to run a service like fly.io if I ever did -- so maybe my secret is out, but I sure would like to know just how much of this fly.io got built on (if any of it), and/or what was turned down.
