This article announces AWS Compute Optimizer's expansion to detect unused NAT Gateway resources, helping customers identify and eliminate idle network infrastructure to reduce costs.

• Compute Optimizer now detects unused NAT Gateways alongside existing idle resource recommendations
• Analyzes 32-day CloudWatch metrics: zero active connections, zero incoming packets from source and destination
• Checks route table associations to avoid flagging disaster recovery and backup NAT Gateways
• Recommendations available in Compute Optimizer console with estimated monthly savings and utilization graphs
• Accessible via GetIdleRecommendations API for programmatic access
• Integrated with AWS Cost Optimization Hub for consolidated optimization view

This expansion enables comprehensive network cost optimization while protecting high-availability and disaster recovery architectures through architectural context analysis.
