Kubernetes had won the container scheduler wars. At GitLab we're all in on making a PaaS based on k8s and our CI/CD and the container registry that is part of GitLab.
(one might even say [1] seems to imply it'll never happen, or at least take a very long time. Also if you read the papers it becomes very clear that "Google Borg" includes a lot of things these days at many levels, from custom ASICs, device firmware (as in standard device, google borg firmware), BIOS firmware, entirely custom sub-kernel code, custom kernels, custom userspace (ie. Google-specific libc that's not optional), ... all of these will turn out to have dependencies on eachother that have to be redone for k8s, could take a while to migrate over)
(although I have not read any papers on it (I'd love some though), I'd bet amazon is in a similar boat, and of course Microsoft is Microsoft)
EC2 is not a container scheduler - it's an IaaS for VMs. The Amazon container PaaS (ECS/EKS) is a layer on top of EC2. And that is being superseded by Fargate which will make the underlying EC2 invisible. If you need a Fargate-like capability now, Azure AKS does it.
Fargate is expensive as hell for long running services. You should only be using it for something that creates value 100% of the time that it is running.

This is very interesting. Could you talk more on this ? There is definitely space for an "opinionated k8s distro with batteries included". I have wished for Swarm to become this....
