 ## Scale requirements when using autoscaler with AKS on Azure Local
 
 > [!NOTE]
-> When autoscaler is enabled, Arc Resource Bridge (ARB) memory configuration determines the supported number of AKS clusters:
-> - **Up to 12 clusters** with an **8 GB ARB**
-> - **Up to 24 clusters** with a **16 GB ARB**
+> When autoscaler is enabled, AKS on Azure Local currently supports a maximum of **12 clusters** per Azure Local environment.
 >
-> If these limits are exceeded, operations such as creating additional clusters or node pools may not succeed. To manage capacity, we recommend deleting unused clusters using [az aksarc delete](/cli/azure/aksarc#az-aksarc-delete).

-> If autoscaler is enabled on an environment that already exceeds these limits, performance may be impacted. Managing to supported limits is recommended.

-To increase ARB memory and support additional clusters when using autoscaler, follow the resizing guide (link pending from Aline Tran).
+> If autoscaler is enabled in an environment that already exceeds the supported cluster count, performance may be impacted. Managing within supported limits is recommended.

-| Max Number of AKS clusters per Azure Local cluster | 12 (8 GB ARB)<br>24 (16 GB ARB) |
-| Number of concurrent AKS cluster creations on an ARB  | 4 |
-| Number of concurrent node pool creations on an ARB  | 4  |
-| Number of concurrent operations across all different AKS clusters such as upgrade/scaling, etc., excluding creating node pool or clusters  | 12 (8 GB ARB)<br>24 (16 GB ARB)  |
+| Maximum number of AKS clusters with autoscaler enabled | 12 |
