  from user workloads.
  Some organizations run critical add-ons or monitoring tools on control plane nodes.
  
  Cluster management tools
  Tools like kubeadm, kops, and Kubespray offer different approaches to deploying and managing clusters,
  each with its own method of component layout and management.
  The flexibility of Kubernetes architecture allows organizations to tailor their clusters to specific needs,
  balancing factors such as operational complexity, performance, and management overhead.
  Customization and extensibility
  Kubernetes architecture allows for significant customization:
  
  Custom schedulers can be deployed to work alongside the default Kubernetes scheduler or to replace it entirely.
  API servers can be extended with CustomResourceDefinitions and API Aggregation.
  Cloud providers can integrate deeply with Kubernetes using the cloud-controller-manager.
