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.

Amazon EC2 Enhances Defense in Depth with Default IMDSv2
Kubernetes has a lot of limitations from a multi tenancy perspective.
It's functional, but I think it's not as polished as the rest of Kubernetes which is why Kubernetes has a multi tenancy SIG that spawned the hierarchical namespace controller (https://github.com/kubernetes-sigs/hierarchical-namespaces) and virtual clusters (https://github.com/kubernetes-sigs/cluster-api-provider-nest...)

Any projects to run Kubernetes inside Kubernetes?
Also https://github.com/kubernetes-sigs/cluster-api-provider-nested, similar approach to vcluster, but part of the K8s project.

Introduction to Multi-Tenancy in Kubernetes
Approach C This approach provides a way to implement hard isolation among Kubernetes tenants who have no trust between them. This provides segregated master plane components for each tenant by creating a mini virtual cluster on the super Kubernetes cluster. Admins can also create custom resources in those virtual clusters as well. This is provided by projects like VirtualCluster and vCluster.
What are some alternatives?
cluster-api-provider-azure - Cluster API implementation for Microsoft Azure
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.
cluster-api-provider-metal3 - Metal³ integration with https://github.com/kubernetes-sigs/cluster-api
kamaji - Kamaji is the Hosted Control Plane Manager for Kubernetes.
cluster-api-provider-vsphere
cluster-api-provider-openstack
cluster-api-provider-digitalocean - The DigitalOcean provider implementation of the Cluster Management API
hierarchical-namespaces - Home of the Hierarchical Namespace Controller (HNC). Adds hierarchical policies and delegated creation to Kubernetes namespaces for improved in-cluster multitenancy.
cluster-api-provider-aws - Kubernetes Cluster API Provider AWS provides consistent deployment and day 2 operations of "self-managed" and EKS Kubernetes clusters on AWS.
