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.

Multi-tenancy in Kubernetes
You could use a container sandbox like gVisor, light virtual machines as containers (Kata containers, firecracker + containerd) or full virtual machines (virtlet as a CRI).

How we reduced Kubernetes Clusters Sprawl by adopting Vclusters: An Introduction
At the end is just a tool which helps to achieve multi tenancy(with all pros and cons) in Kubernetes. It takes a different approach from capsule for example as you have a dedicated control plane for each tenant which means you have an isolated api server that you can spin up in a matter of seconds and lets you also achieve better resource utilizations by using the same nodes shared among all tenants
- Is it anti-pattern to have multiple environments under a single namespace?
-
k8s based platform
For multi tenancy you could use this: https://github.com/clastix/capsule
- RBAC for developer self-service?
What are some alternatives?
kamaji - Kamaji is the Hosted Control Plane Manager for Kubernetes.
vcluster - vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.
