 For example, Gardener uses them to setup and maintain the networks, security groups, subnets, etc., while the [cloud-controller-manager](https://kubernetes.io/docs/concepts/architecture/cloud-controller/) uses them to reconcile load balancers and routes, and the [CSI controller](https://kubernetes-csi.github.io/docs/) uses them to reconcile volumes and disks.
 
 Depending on the cloud provider, the required [data keys of the `Secret` differ](https://github.com/gardener/gardener/blob/master/example/70-secret-provider.yaml).

 When using the term `Machine image` in the following, we refer to the OS version that comes with the machine image of the node/worker pool of a Gardener Shoot cluster.
 As such, we are not referring to the `CloudProvider` specific machine image like the [`AMI`](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AMIs.html) for AWS.
-For more information on how Gardener maps machine image versions to `CloudProvider` specific machine images, take a look at the individual gardener extension providers, such as the [provider for AWS](https://github.com/gardener/gardener-extension-provider-aws/blob/master/docs/usage-as-operator.md).

 Gardener should be configured accordingly to reflect the "logical state" of a version.
 It should be possible to define the Kubernetes or Machine image versions that still receive bug fixes and security patches, and also vice-versa to define the version that are out-of-maintenance and are potentially vulnerable.
