Starting from **Denodo 8.0** , Solution Manager provides a new feature called Automated Cloud Mode that automates creation of Auto Scaling groups.
For more information you can take a look at the[ Automated Cloud Mode](https://community.denodo.com/docs/html/browse/8.0/solution_manager/administration/automated_aws/automated_aws) section of the Solution Manager Administration Guide.
However, from the question I understand that you are facing an error related to scale-in process. In such situations I would check the relevant log files located under ** <SOLUTION_MANAGER_HOME>/logs folder** for more details.
Suppose, If you still need help and if you are a valid support user then you can raise a support case in [Denodo Support Site](https://support.denodo.com/) so that our support team can help you.
Hope this helps !
