SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Systematically reduces AWS cloud spend by right-sizing over-provisioned compute, eliminating idle or orphaned resources, and enforcing cost-allocation tagging, while guiding commitments to Savings Plans and Reserved Instances.

Core Features & Use Cases

  • Eliminate waste: detect unattached volumes, idle EIPs, stale snapshots, idle NAT gateways, and idle RDS/EC2 instances.
  • Right-size and modernize: leverage utilization signals to downsize instances and adopt cheaper SKUs or storage tiers.
  • Commit with guardrails: recommend Savings Plans or RI coverage based on stable baseline, with safety checks.
  • Attribute and showback: enforce tagging governance to enable cost attribution and accountability.
  • Input data and outputs: produce a ranked savings plan report and a rollout plan that includes risk and owner.
  • Use Case: FinOps teams reduce monthly spend across accounts by ~20-50% with rapid wins and governance.

Quick Start

Load your inventory JSON or sample from the repo, run the cost optimization workflow to identify the highest-impact savings.

Frequently Asked Questions about aws-cost-optimizer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find and eliminate idle AWS resources to cut cloud spend?▼

To cut AWS cloud spend, you can detect idle resources like unattached EBS volumes, idle Elastic IPs, stale snapshots, and idle NAT gateways by analyzing utilization metrics against baseline data to produce a prioritized savings plan.

Can I automatically right-size over-provisioned EC2 and RDS instances?▼

Yes, you can right-size over-provisioned EC2 and RDS instances by leveraging utilization signals like p95 CPU over observed days to recommend downsizing instances and adopting cheaper storage tiers or SKUs.

How do I choose between AWS Savings Plans and Reserved Instances?▼

Choosing between AWS Savings Plans and Reserved Instances involves evaluating your stable baseline usage with safety checks to recommend commitment coverage that maximizes savings without risking over-commitment.

How do I enforce cost-allocation tagging for AWS showback and accountability?▼

You enforce cost-allocation tagging by applying tagging governance workflows across your AWS accounts, which enables accurate cost attribution, accountability, and showback for resource owners.

What data do I need to start AWS cost optimization?▼

To start AWS cost optimization, you need baseline data inputs and utilization metrics, such as an inventory JSON file containing your resources, to generate a ranked savings plan with estimated monthly savings and risk.

What is the expected monthly savings from a systematic AWS FinOps workflow?▼

A systematic AWS FinOps workflow can reduce monthly cloud spend across accounts by approximately 20-50% by delivering rapid wins through waste elimination, compute right-sizing, and guided commitments.
