It's built on-top of the Kubernetes API server runtime and deploys virtual machines and tenant networks, you can see the Kubernetes cluster I deploy using IaC YAML manifests here - https://github.com/ordiri/ordiri/tree/master/ordiri/examples...
It powers all my publicly hosted, ipv6 only services - https://blog.dmann.xyz for example, it's 1000% over kill but a fun project none the less :)
