NAT Gateway Costs High?

The cost signal

NAT Gateway charges can surprise small teams because hourly cost and processed data charges continue even when traffic is not tied to obvious application features. CloudPrune can scan NAT gateways, route tables, endpoint candidates, and traffic context before suggesting gateway endpoints, interface endpoints, subnet routing changes, or consolidation.

Review method: Read-only evidence first, followed by owner review, rollback planning, and post-change validation.

How to verify manually

Open AWS Billing and Cost Explorer to confirm the service driving the spend.
Use the AWS console view for the affected service to identify candidate resources.
Run a read-only AWS CLI inventory command and export the resource IDs before changing anything.
Compare age, attachment, traffic, retention, and recent usage signals before deciding on cleanup.

Impact and rollback

Classify whether the action can affect production traffic, data retention, compliance, or incident response.
Prefer dry-run review first. For storage deletion, create or verify a snapshot/export when rollback matters.
Schedule changes with an owner and a validation window. Stop if the blast radius is unclear.
Keep the previous configuration or snapshot reference until post-change metrics are stable.
