# Support for scaling in cloud-based virtualization platforms

When NGFW 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 Firewalls from the cloud environment, and in the Management Client, the Cloud Auto-Scaled Firewalls are automatically added to Cloud Auto-Scaled Group elements. You can monitor the Cloud Auto-Scaled Firewalls in the Home View, for example.

## Limitations

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