Thanks, that was informative. Do you have a reference that you'd recommend about the details of how the big names that you've mentioned are doing multitenant Kubernetes? I'd love to read more about it.
Oh, sorry, that was tongue in the cheek. They are cloud providers, and as such they provide costumers with separate cluster.
The aks-engine repo let you peep to what goes behind the scenes, but this is not the kind of beast you will grow at home - it is a public cloud provider with global scale, with the expected level of complexity and engineering. It is available on: https://github.com/Azure/aks-engine
btw. in hard multitenant k8s you can even go as wide as using a "master" cluster that contains the control plane of another cluster. actually you need the right network cni for that.
