5. Auto Scaling

Enable or disable autoscaling
Set minimum and maximum number of instances
Configure scaling parameters:
- Cooldown: Time (in minutes) LayerOps waits between two scaling operations or instance replacements
- CPU High Limit: When CPU usage reaches this percentage (e.g., 80%), LayerOps triggers a scale up
- RAM High Limit: When RAM usage reaches this percentage (e.g., 80%), LayerOps triggers a scale up
- Instance Unused: Time (in minutes) an instance must be unused before triggering a scale down. An instance is considered unused when it's not running any services.

6. Down Strategy

Enable or disable automatic replacement of down instances
Set delay (in minutes) before an instance is considered down and replaced

Please note that, depending on the cloud provider, the time it takes to create an instance and make it available on the network may vary.If you take 5 minutes, and the instance creation time with this provider is greater than 5 minutes, LayerOps will attempt a re-creation after deleting the first attempt, as long as the instance is not created and available.
