Firecracker internals: deep dive inside the technology powering AWS Lambda(2021)
There is this project, which I have never used, but seems promising. https://github.com/firecracker-microvm/firecracker-container...

Firecracker MicroVMs
How does that compare to firecracker-containerd?
https://github.com/firecracker-microvm/firecracker-container...
This repository enables the use of a container runtime, containerd, to manage Firecracker microVMs. Like traditional containers, Firecracker microVMs offer fast start-up and shut-down and minimal overhead. Unlike traditional containers, however, they can provide an additional layer of isolation via the KVM hypervisor.

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.

BuildBuddy (YC W20) | Engineering | Remote, Bay Area | Full-Time
BuildBuddy was founded to give anyone a "Google-style" development environment in minutes. Today we're solving a small piece of this problem with an open-core remote build execution platform for Bazel - but our ambitions are much larger. Our mission is to take the world-class engineering tools that are only available to employees of large companies and make them available to everyone. Check it out at: https://buildbuddy.io/
Come join us and shape the future of how engineers build and test software! You’ll write and ship open-source code, own production systems used every day by 1000s of engineers at big companies, and help us shape the future of the product. You'll work with and learn from a team that's built software at both successful startups and FAANG companies. Your skillset will grow and you'll join a team excited to solve problems in the developer tool space.
Our tech stack is simple, stable, scalable: Golang, Redis, MySQL, Protobuf, React, Typescript.
