Deleting an Application

When an application is no longer needed, you can delete it from Quant Cloud. However, this is a permanent action that removes the application and all its associated resources, so it’s important to understand the process and implications.

Before You Delete

Backup Critical Data Ensure you’ve backed up any important data from your application’s environments, including databases and persistent storage volumes. Once deleted, this data cannot be recovered through the Quant Cloud interface.

Inform Your Team If others are using or depending on this application, make sure they’re aware of the planned deletion and have time to prepare or migrate to alternatives.

Consider Alternatives If you might need the application again later, consider stopping the environments instead of full deletion. You can also export your configuration settings to recreate the application if needed.

Understanding the Deletion Process

Quant Cloud includes a protective mechanism to prevent accidental deletion of production applications. You cannot delete an entire application while other environments exist - you must delete all non-production environments first, leaving only the production environment.

Environment Deletion Order

1. Delete staging, development, and other non-production environments first
2. Delete the production environment last, which will remove the entire application

Caution

This two-step process is intentionally designed to make you think twice before deleting production applications. It ensures you’re making a deliberate decision rather than accidentally removing critical infrastructure.

Steps to Delete Environments and Applications

Deleting Individual Environments

1. Navigate to your Applications list
2. Find the application and click “Manage Environments”
3. Select the environment you want to delete
4. Look for the “Delete Environment” option in the environment settings
5. Confirm the deletion when prompted

Deleting the Application Once all non-production environments are deleted:

1. Navigate to the production environment settings
2. Find the “Delete Environment” option
3. Confirm the deletion - this will remove the entire application

Confirmation Process The system will ask you to confirm each deletion, often requiring you to type the environment or application name to proceed. Read these confirmation messages carefully as they explain exactly what will be removed.

What Gets Deleted

When you delete an application, Quant Cloud removes:

• All environments and their running containers
• Associated databases (data will be permanently lost)
• Persistent storage volumes (data will be permanently lost)
• Environment variables and secrets
• Logs and metrics history
• Scheduled tasks and cron jobs
• Any custom domains or SSL certificates

The deletion process may take several minutes depending on the number of resources involved. The application will disappear from your Applications list once the process completes.

Important Considerations

Permanent Action Deletion is irreversible. There’s no way to recover a deleted application or its data through Quant Cloud once the process is complete.

Resource Cleanup Quant Cloud automatically cleans up all associated cloud resources to prevent ongoing charges. You don’t need to manually remove anything from the underlying infrastructure.

Alternative to Deletion If you’re unsure about permanently removing an application, consider stopping all environments instead. This takes the application offline and stops resource consumption while preserving the configuration and data for potential future use.

Best Practices

• Always backup critical data before deletion
• Delete applications during maintenance windows when possible
• Document the deletion for your team’s records
• Consider the impact on any dependent services or integrations

Remember, the production environment protection is there for your safety - use this time to double-check that you’re making the right decision for your application lifecycle.
