@webframp/aws-cost-audit

v2026.04.14.2

AWS cost audit workflow — identifies infrastructure waste by combining Cost Explorer spend data, resource inventory, and networking inspection. Generates a report with savings recommendations.

Quick Start

swamp extension pull @webframp/aws-cost-audit

swamp model create @webframp/aws/cost-explorer aws-costs --global-arg region=us-east-1
swamp model create @webframp/aws/networking aws-networking --global-arg region=us-east-1
swamp model create @webframp/aws/inventory aws-inventory --global-arg region=us-east-1

swamp workflow run @webframp/cost-audit

AWS cost audit workflow — gathers spend data from Cost Explorer, resource inventory, and networking details, then enriches with CloudWatch metrics and identifies top cost drivers. Results feed into the cost-audit report for savings recommendations.
