Discover more about what's new at AWS with AWS Trusted Advisor now delivers more accurate unused NAT Gateway checks powered by AWS Compute Optimizer

AWS' platform is a leading cloud computing platform, offering insights into cloud infrastructure, services, and solutions for developers, businesses, and IT professionals. Through articles, whitepapers, and documentation, AWS offers insights into cloud architecture, serverless computing, and machine learning on AWS. Developers and architects can learn about AWS services like EC2, S3, Lambda, and more to build scalable, secure, and cost-effective cloud applications.

AWS Trusted Advisor has improved its unused NAT Gateway detection by integrating AWS Compute Optimizer capabilities. The enhanced check analyzes additional CloudWatch metrics over a 32-day lookback period and verifies route table associations to reduce false positives. Each recommendation includes estimated monthly cost savings to help prioritize cleanup. The feature is available in all supported AWS Regions, but requires organizations to be opted into Cost Optimization Hub and Compute Optimizer.
