  from more requests to the control plane and worker nodes or scale down to reduce unused
  resources.
  
  Security and access management: You have full admin privileges on your own
  Kubernetes learning cluster. But shared clusters with important workloads, and
  more than one or two users, require a more refined approach to who and what can
  access cluster resources. You can use role-based access control
  (RBAC) and other
  security mechanisms to make sure that users and workloads can get access to the
  resources they need, while keeping workloads, and the cluster itself, secure.
  You can set limits on the resources that users and workloads can access
  by managing policies and
  container resources.
  
  Before building a Kubernetes production environment on your own, consider
  handing off some or all of this job to
  Turnkey Cloud Solutions
  providers or other Kubernetes Partners.
  Options include:
  
  Serverless: Just run workloads on third-party equipment without managing
  a cluster at all. You will be charged for things like CPU usage, memory, and
  disk requests.
  Managed control plane: Let the provider manage the scale and availability
  of the cluster's control plane, as well as handle patches and upgrades.
  Managed worker nodes: Configure pools of nodes to meet your needs,
  then the provider makes sure those nodes are available and ready to implement
  upgrades when needed.
  Integration: There are providers that integrate Kubernetes with other
  services you may need, such as storage, container registries, authentication
  methods, and development tools.
  
  Whether you build a production Kubernetes cluster yourself or work with
  partners, review the following sections to evaluate your needs as they relate
  to your cluster’s control plane, worker nodes, user access, and
  workload resources.
  Production cluster setup
  In a production-quality Kubernetes cluster, the control plane manages the
