How I Built an AI Agent That Cut My AWS Bill by 40% (CrewAI + Bedrock)

Description and use

A CrewAI + Bedrock agent automatically scans an AWS account, identifies waste, and produces a markdown report with precise savings, cutting the bill by 40 %.

Problem

AWS accounts often accumulate hidden costs from orphaned resources, idle IPs, and outdated storage, making manual audits time‑consuming and error‑prone.

Outcome

The system identified $125/month in waste, including orphaned EBS volumes, unused Elastic IPs, and a non‑reserved EC2 instance, enabling quick actions that saved $40/month before lunch.

Workflow

• Clone the repo and install dependencies
• Set AWS_DEFAULT_REGION environment variable
• Run main.py to execute the three agents sequentially
• Review the generated markdown report
• Act on quick‑win recommendations (delete orphaned volumes, release unused IPs, reserve instances)

Evidence

It found $125/month I was burning for nothing.

Source

Three orphaned EBS volumes: $33/month. Two unattached Elastic IPs: $7.20/month.
