 An Azure Kubernetes Service (AKS) cluster will periodically need to be updated to ensure security and compatibility with the latest features. There are two components of an AKS cluster that are necessary to maintain:
 
-- *Cluster Kubernetes version*: Part of the AKS cluster lifecycle involves performing upgrades to the latest Kubernetes version. It’s important you upgrade to apply the latest security releases and to get access to the latest Kubernetes features, as well as to stay within the [AKS support window][supported-k8s-versions].

 - *Node image version*: AKS regularly provides new node images with the latest OS and runtime updates. It's beneficial to upgrade your nodes' images regularly to ensure support for the latest AKS features and to apply essential security patches and hot fixes.
 
 For Linux nodes, node image security patches and hotfixes may be performed without your initiation as *unattended updates*. These updates are automatically applied, but AKS doesn't automatically reboot your Linux nodes to complete the update process. You're required to use a tool like [kured][node-updates-kured] or [node image upgrade][node-image-upgrade] to reboot the nodes and complete the cycle.
