Infrastructure Verification

About

The Infrastructure Verification skill empowers developers to proactively audit AWS VPC configurations, NAT Gateway capacities, and service endpoints before and after deployments. By applying the Infrastructure-Application Contract principle, it helps identify deterministic failure patterns—such as Lambda connection timeouts caused by missing S3 VPC endpoints—preventing common production bottlenecks and ensuring that network paths are correctly provisioned for serverless workloads. It provides structured workflows for diagnosing connectivity issues that often bypass standard application debugging.

Key Features

• Post-deployment infrastructure smoke testing and validation
• Network path validation for Lambda egress to AWS services
• Deterministic failure pattern recognition for accelerated debugging
• NAT Gateway saturation and connection limit diagnosis
• 0 GitHub stars
• Automated VPC endpoint and route table connectivity audits

Use Cases

• Debugging Lambda-in-VPC connection timeouts and S3 access issues
• Validating network infrastructure after Terraform or CloudFormation updates
• Pre-scaling checks to ensure NAT Gateways can handle high concurrency
