Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How does managed kubernetes providers hide the control plane?
Now, if you want to dig further on how cloud providers operate, like I said, most are actually using Kubernetes to automate the client control plane management. There is a cloud-neutral project for this out there called Gardener, they have a few architecture documents which explain the concept a bit further. In their garden metaphor, the seed cluster hosts the client control planes, and the shoot clusters are the client clusters (which are only made of worker nodes, no control-plane node). Another more specialized implementation is Kubernikus for OpenStack.

Can we use a worker node of one kubernetes cluster as master node of another k8s cluster?
Gardener does exactly that. One global cluster manages smaller per-region/cloud provider management clusters and those will contain the control planes of your workload clusters. This way you can have like 10 000 clusters and not deal with multi-tenant issues. One workload = 1 cluster.

Over a fifty K8s clusters?
We had cluster of cluster style management managing 100s of cluster. Check out https://github.com/gardener/gardener for an inspiration
- Why aren't there any manged Kubernetes Control Plane as a Service offering out there?

Amazon EKS Anywhere
How does this compare against simply using Gardener [0]?

EKS Anywhere: The What, The Why and The How
EKS Anywhere builds on the strengths of Amazon EKS Distro, the same open-source distribution of Kubernetes that is used by Amazon EKS on the cloud, thus fostering consistency and compatibility between clusters both on AWS as well as on-premises.

Amazon EKS Anywhere
yes im aware of bmctl. however you dont have control over the kubernetes distro that's running.
is there anything similar to https://github.com/aws/eks-distro ?
EKS-A focuses on cluster management for HA environments. By default we use 3 etcd nodes, 2 control plane nodes, and 3 worker nodes. It uses cilium as the default CNI and Cluster API controllers for continual cluster state management. It has some optional configuration for a flux controller and OIDC authentication but it doesn't add default services or workloads. EKS-A also uses EKS Distro which is the open source Kubernetes distribution we run in hosted EKS.
