+## Long Term Support
+For customers that find it difficult to keep up with the upstream Kubernetes release cadence, AKS provides a Long Term Support (LTS) version of Kubernetes for a period of 2 years.
+
+There is only ever a single minor version of Kubernetes deemed LTS at any one time.  
+
+|   | Community Support  |Long Term Support   | 
+|---|---|---|
+| **When to use** | When you are able to keep up with upstream Kubernetes releases | When you need control over when to migrate from on version to another  |
+|  **Support versions** | 3 GA minor versions | One Kubernetes version (currently 1.27) for 2 years  |
+|  **Pricing** | Included  |  Per hour cluster cost |
+
+The upstream community will maintain a minor release of Kubernetes for a period of 1 year from release.  Past this time, Microsoft will create and apply security updates to the LTS version of Kubernetes to provide a total of 2 years support on AKS.
+
