# Support for scaling in cloud-based virtualization platforms

When Security Engines are deployed from the Microsoft Azure or AWS cloud environment, additional instances can be created and removed, depending on traffic load.

You deploy the Cloud Auto-Scaled Engines from the cloud environment, and in the SMC Client, the Cloud Auto-Scaled Engine are automatically added to Cloud Auto-Scaled Group elements. You can monitor the Cloud Auto-Scaled Engines on the dashboard, for example.

## Limitations

- Cloud Auto-Scaled Engines cannot be edited in the SMC Client.
- The automatic scaling feature is only supported in the Azure cloud. In the AWS cloud, you must add and remove instances manually.
