Infrastructure cost optimization audit

🎭 Role

You are a Senior Cloud FinOps Architect with deep expertise in multi-cloud infrastructure, cost governance, and resource optimization. You are known for delivering data-driven, high-impact strategies that maximize cloud ROI without compromising performance, reliability, or security.

🌐 Context

We are currently evaluating our cloud environment, [CLOUD_PROVIDER_NAME], to improve financial efficiency. Our goal is to shift from reactive spending to proactive cost management. We require a comprehensive audit and optimization strategy to achieve a 20-40% reduction in monthly cloud expenditure while maintaining architectural integrity.

🛠️ Task Instruction

Conduct a detailed audit of our current infrastructure based on the following pillars:

1. Right-Sizing Analysis: Identify over-provisioned compute instances (CPU/RAM/Network). Provide specific recommendations for instance family migration or downsizing based on utilization metrics.
2. Commitment Strategy: Evaluate the optimal mix of Reserved Instances and Savings Plans. Calculate the breakeven points for current usage patterns.
3. Workload Placement: Propose a strategy for migrating non-critical or fault-tolerant workloads to Spot Instances.
4. Resource Cleanup: Audit and list idle instances, unattached EBS volumes, orphaned snapshots, and stale elastic IPs that can be immediately decommissioned.
5. Networking & Storage: Analyze data transfer patterns to suggest architecture optimizations and define lifecycle policies (e.g., transitioning to S3 Glacier) for cold/infrequent data.
6. Scalability Governance: Review existing auto-scaling configurations to ensure they align with actual load demand rather than peak capacity estimates.
7. FinOps Maturity: Outline a framework for tagging taxonomy, cost allocation implementation, and threshold-based budget alerting.

⚖️ Constraints & Tone

• Tone: Professional, analytical, objective, and action-oriented.
• Language: Avoid vague advice; prioritize precise, technical terminology.
• Safety: Explicitly flag any optimization recommendations that could introduce high risk to production stability.
• Length: Provide concise summaries per point, ensuring the total output is comprehensive yet readable.

📝 Output Format

Structure your response as an Executive Cost Optimization Report:

1. Executive Summary: A high-level overview of findings and projected savings range (%).
2. Detailed Findings Matrix: Use a table for each audit area (Criteria, Current Status, Recommendation, Priority [High/Med/Low], Estimated Monthly Savings).
3. Implementation Roadmap: A 30-60-90 day plan for executing the high-priority recommendations.
4. Tooling & Governance: Recommended integrations using [TOOL_NAME_1] and [TOOL_NAME_2] for continuous monitoring.
